There is a lot of work that needs to be done in the battle to prepare for pregnancy. Pregnancy is a matter of two people, so make a plan together with your partner and carefully fill out a pre-conception self-examination form. Based on this worksheet, the doctor will be able to quickly understand the physical condition of both partners and give the most effective advice on the “baby-making plan”. Only when all the indicators of the preconception examination are passed, we will be able to successfully advance to the status of parents-to-be. The issues that need to be considered for a pregnant mother are: lifestyle habits, family history, sexual history, medical history and menstrual history. I. Menstrual history 1. Do you know how many days your normal menstrual cycle is? Knowing the number of days of the cycle is the only way to better deduce the ovulation period. It is normal to have an interval of 21-40 days between the first day of this menstrual cycle and the first day of the next menstrual cycle. Each person has a different number of days for the egg to mature and therefore the menstrual cycle is different. The day of ovulation is usually 14 days before the next menstrual period. 2. Is the menstrual cycle regular? Irregular menstrual cycles are usually caused by endocrine disorders. It may indicate thyroid problems, lactogen or polycystic ovary syndrome. You should see a doctor promptly. 3. Is the amount of bleeding in the menstrual cycle normal? Is it more or less? Generally speaking, the amount of bleeding varies from month to month, but if you bleed for a long time, it is likely to indicate ovulation problems; sudden, heavy bleeding is likely to indicate the presence of fibroids in the uterus. 4. Is there bleeding between menstrual cycles? Or is there unexplained bleeding? If the bleeding is during ovulation, it is because individual women with low estrogen level cannot maintain the growth of the endometrium, so you can take oral estrogen supplement and pay attention to rest; if it is frequent menstruation, you should go to the hospital for further examination to confirm the diagnosis. 5. Do you feel severe pelvic pain or abdominal cramps during the days of menstruation? Most women will feel uncomfortable during or around the days of menstruation, and mild pain is not too important, so pay attention to keep warm. However, severe pain is a sign of endometriosis or pelvic adhesions. You should go to a gynecological examination. 6.How old is the first menstruation? Is there any menstruation after the age of 18? If the menarche occurs after the age of 18, it indicates that there may be problems such as unstable hormone levels or endocrine disorders. 2. Medical history 1. Do you often feel a heavy feeling in your pelvis? This is likely to be a sign of fibroids, please go to the hospital for examination in time. 2.Is it endometriosis? Endometriosis can cause irregular menstruation, painful periods, and even female infertility. It can be treated with pseudopregnancy therapy. 3. Is it diagnosed with polycystic ovary syndrome? Polycystic ovary syndrome is caused by endocrine disorder, which can lead to irregular ovulation, sparse ovulation, or even non-ovulation, making conception more difficult. Actively receive treatment from your doctor and arrange ultrasound to monitor ovulation if necessary. 4. Have you ever had surgery on your pelvis or lower back? For example, appendicitis surgery, etc. Surgical procedures sometimes leave scarring that can affect conception. Please consult your obstetrician and gynecologist before conception. 5. Have you ever had a tubal ligation? Tubal ligation may cause scar tissue, which may affect pregnancy and increase the risk of ectopic pregnancy. Please consult your obstetrician and gynecologist before pregnancy. 6. Do you suffer from chronic diseases such as diabetes, thyroid disease or hypertension? These chronic diseases and their treatment may affect pregnancy or may be a high risk pregnancy. You should wait for treatment and stabilization before considering childbirth, and consult your doctor before conception. 7. Are you taking any medications? Steroids or other medications, including herbal medicines, can have an effect on pregnancy. Drugs that have an effect on conception should be stopped for at least 6 months before considering pregnancy. 8. Have you ever been pregnant, given birth, or had any complications during pregnancy? If you have been pregnant before or have given birth, your body is not well conditioned, which may worsen your health condition and affect your pregnancy again. 9.Have you ever had a history of miscarriage? How many times have there been? What are the reasons for miscarriage? Repeated miscarriages are a sign of fertility problems, which means your body is not suitable for pregnancy or you need extra help in the process of pregnancy. It is important to take rest after miscarriage and consult your doctor for detailed information about the causes of recurrent miscarriage to achieve the right treatment. III. Sexual history 1. Have you ever used an IUD? The IUD is a foreign object that may cause rejection and lead to an increased incidence of infectious pelvic diseases. 2. Have you ever been infected with sexually transmitted diseases? Which one is it? Both tubal problems and infectious pelvic disease are associated with infection with chlamydia and gonorrhea virus. Pregnancy should be considered after the disease is cured and consult with an obstetrician and gynecologist before conception. 3. Do I feel pain when I kiss my husband in AA? This is a sign of endometriosis or pelvic adhesions causing infectious pelvic disease. Please consult a gynecologist. 4.Does my vagina bleed when I have AA with my husband? There may be many reasons for bleeding after intercourse, such as vaginal tearing, reproductive tract infection or problems with the uterus and cervix, such as cervicitis, cervical polyps or abnormal cervical development, etc. Please pay attention to the posture during AA and consult a gynecologist if there is abnormal bleeding. 4. lifestyle habits 1. how many cups of caffeinated beverages, such as tea, coffee or soda, do you drink on average every day? There are experiments to prove that the more coffee a woman drinks, the less likely she is to get pregnant. Even when pregnant, excessive coffee intake can affect fetal development. It is best to drink less or not to drink at all. 2. Do you like to drink alcohol? You should abstain from alcohol during the preparation and conception period, because some studies have confirmed that drinking alcohol reduces the chances of conception. During pregnancy, especially early pregnancy, which is an important period for fetal organ differentiation, you should also abstain from alcohol. 3. Do you like smoking? Some studies have shown that the nicotine in cigarettes can lower the level of estrogen in women’s bodies and affect conception. 4. Is your weight normal? Are you underweight or overweight? BMI should be kept at 18.5 ≤ BMI ≤ 23.9. Being too thin or overweight can cause endocrine problems, which can disrupt a woman’s ovulation cycle. Pay more attention to your physical condition before pregnancy, gain weight if you are too thin and lose weight if you are too fat. Body mass index (BMI) = weight (kg) ÷ height^2 (m) V. Family medical history Has anyone in the family had a child with genetic defects or had a stillbirth? You can talk to both parents or relatives, especially those couples who do not have children. And pre-conception fertility genetic counseling, prenatal genetic disease monitoring if necessary, through the pre-conception self-examination form, in order to quickly understand the physical condition of the couple, a comprehensive understanding of their own in order to faster pregnancy, but also to give the most effective advice on the “baby-making plan”.
