Preparing for Pregnancy in 3 Months: Checklist of Tests, Habits, and Workouts

Three months before conception is not just “just in case,” or about taking vitamins. During this time, you can check your health, balance hormones, replenish iron and vitamin deficiencies, undergo treatment if necessary, and reduce risks during pregnancy. Below is a clear plan to help approach conception calmly and well-prepared.

What is preconception preparation and why is it necessary

Preparing for pregnancy is not an unnecessary precaution, but a way to reduce real risks. Several months before conception, you can identify hidden health issues, adjust hormones, assess ovarian reserve, and understand the fertility status of the couple.

Pregnancy is a serious restructuring of the body. The load on the reproductive system, thyroid gland, heart, and blood vessels increases. If a woman approaches conception with iron deficiency, elevated TSH, or untreated infections, the risk of complications is higher. This can affect both the course of pregnancy and the development of the child.

Preparation is not about finding diagnoses, but caring for health. Its goal is to create conditions in which conception and pregnancy will proceed as favorably as possible.

Where to start preparing for pregnancy

Start with a gynecologist consultation. During the visit, the doctor will ask about your cycle, ovulation, past illnesses and surgeries, clarify family history, and assess the overall state of the reproductive system.

A personalized examination plan is then created. There is no universal list of tests: the extent of preparation depends on the woman’s age, chronic diseases, and previous research results.

If necessary, the doctor will refer you to other specialists — for example, an endocrinologist if there are concerns about thyroid function or blood sugar levels.

Don’t delay the visit. After 35 years or in case of conception difficulties, time becomes an important factor, and planning is best started in advance.

Examination before conception: complete list of tests

Pre-conception screening helps identify conditions that may affect pregnancy. Below is a basic list of examinations.

General Clinical Tests

Complete blood count
Biochemical blood test
Urinalysis
Rhesus factor and blood type determination

A complete blood count can detect anemia and inflammatory processes. Ferritin indicates if there is an iron deficiency. This is important for preventing fetal hypoxia and gestational diabetes.

Hormonal Profile

TSH
Prolactin
FSH
LH
Anti-Müllerian Hormone

The hormonal profile assesses hormone levels and ovarian reserve. If TSH is above 2.5 mU/L, a doctor may recommend treatment before pregnancy.

Infection Screening

HIV
Syphilis
Hepatitis B and C
Flora smears
Sexually transmitted infections

It’s also important to check rubella antibodies. If there’s no immunity, vaccination is recommended before conception.

Instrumental Research

Pelvic ultrasound
Pelvic ultrasound allows assessment of the uterus, endometrium, ovarian structure, and confirmation of ovulation.

Pap test and cervical cytology — to rule out precancerous changes.

Genetic Research

Genetic counseling is conducted as indicated. This is particularly relevant if there are hereditary diseases in relatives or recurrent pregnancy losses.

Table: Key Tests at the Planning Stage

Analysis	Purpose	When to take
Complete blood count	To rule out anemia	3 months before conception
Ferritin	To identify iron deficiency	Before starting vitamins
TSH	Assess thyroid function	Before pregnancy
Anti-Müllerian hormone	Evaluate ovarian reserve	As indicated
Rubella antibodies	Check immunity	Before vaccination

Vitamins and minerals three months before conception

Vitamins for preparing for pregnancy are not a universal ‘just in case’ set. Their prescription depends on test results.

Folic acid is mandatory. Taking folic acid reduces the risk of neural tube defects in the baby. The standard dose is 400–800 mcg per day.

Vitamin D is prescribed for its deficiency.
Iodine – if there are no contraindications.
Iron – if ferritin is reduced.

Important: vitamin intake should be coordinated with a doctor. Excessive vitamin support does not increase conception chances.

The diet should include vegetables and fruits, lean meat, and fish. A balanced diet is the foundation for preparing the body for pregnancy.

Lifestyle and Physical Activity: not “to lose weight for summer,” but to prepare the body for pregnancy

You can take all the tests, buy the best vitamins for preparing for pregnancy, and still keep sleeping for only 5 hours, live in stress, and move only from the car to the office.

Preparing for pregnancy is not just about blood tests and hormone levels. It’s about the state in which a woman’s body enters pregnancy.

Pregnancy is physiological, yet still a stress for the body. Blood volume increases, hormonal balance changes, and the load on the heart, thyroid gland, and joints increases. If the body is already working “at its limit,” the risk of complications during pregnancy is higher.

How Much and How to Move During the Planning Stage

There’s no need to sign up for a marathon and urgently “do crunches for conception.” Regularity is more important.

Optimal:

• 150–300 minutes of moderate physical activity per week
  
• 2–3 strength training sessions without extreme weights
  
• yoga or pilates for working on pelvic floor muscles
  
• regular walks — simple, daily, without fanaticism
  
• Physical activity improves circulation in the pelvic organs, helps normalize the cycle, and supports ovulation. In overweight women, losing just 5–7% of body weight can restore ovulation without medication. Our MomsLab app includes a special course on preparing for pregnancy, featuring materials on nutrition, workouts, healthy sleep, test checklists, and relaxation techniques.

It is important not to fall into the opposite extreme. Excessive cardio, strict calorie deficiency, chronic fatigue can suppress ovulation. Preparing the body for pregnancy is about balance, not a feat.

Weight: Why It Really Matters

Being overweight increases the risk of gestational diabetes, preeclampsia, and birth complications. Underweight can disrupt hormone balance and cycle.

The planning stage is the best time to gently normalize weight. Not through ‘detoxes’ and water marathons, but through a proper diet: vegetables and fruits, fish, lean meat, complex carbohydrates. This is not a diet, but a foundation for the health of the future child.

Sleep and Stress — An Underrated Factor in Fertility

Chronic stress increases cortisol levels, which can interfere with ovulation regulation. Lack of sleep affects hormonal balance and increases the risk of complications during pregnancy.

Sleeping at least 7 hours is not just a “checkbox” recommendation. It is part of pre-gravid preparation.

Smoking and Alcohol

Quitting smoking and abstaining from alcohol is an essential step. Even “rarely and on special occasions” during planning can reduce fertility and increase the risk of adverse pregnancy outcomes.

Important! The body doesn’t “cleanse in a week.” The sooner alcohol and nicotine intake is stopped, the better for future conception.

Men’s Preparation: Without This, the Checklist Is Incomplete

A common mistake is to assume that pregnancy preparation is solely the woman’s responsibility. About 40% of conception difficulties are related to the male factor.

Sperm quality is formed in about 74 days. This means that a man’s lifestyle three months before conception directly affects the couple’s chances.

What a man should do during the planning stage

• undergo a spermogram
  
• take a blood test for HIV, syphilis, hepatitis
  
• quit smoking
  
• limit alcohol
  
• normalize weight
  
• reduce chronic stress
  

Sperm quality is sensitive to overheating, alcohol, obesity, and inflammatory diseases. Preparing for pregnancy is truly a joint effort.

When a man participates in planning, it’s not just about tests. It’s about support, about the woman’s psychological stability, about reducing anxiety during the conception stage.

Joint preparation increases the chances of natural conception and reduces the risk of complications during pregnancy.

Preparation for IVF: When Planning Becomes a Medical Strategy

If pregnancy does not occur naturally or there are medical indications, the stage of IVF preparation begins.

Preparation for IVF is always more detailed. The reproductive specialist evaluates the hormonal profile, TSH level, prolactin, anti-Müllerian hormone, endometrium condition, ovarian reserve.

Before the IVF program, it may be necessary to treat inflammatory diseases, correct hormone levels, and normalize iron and vitamin D levels.

Preparation for IVF is not just about “entering the program.” It is a structured planning stage, where each examination is aimed at reducing the risk of failure and increasing the chances of pregnancy.

It’s important to understand: even with IVF, lifestyle remains a significant factor. Sleep, stress, nutrition, weight — all these continue to impact the outcome.
