“If you want to get pregnant, find the doctor first, then your husband”, this is one of those phrases that is not true! When facing a second baby, the couple is actually under quite a lot of psychological pressure. The first one is healthy, do not want the second one is not healthy; the first one is not healthy, more can not tolerate the second one is not healthy. The most for the “carrier” of the baby – the mother, is the most should be a good assessment of the state of this “carrier”. If you have already made up your mind to have a baby, then it is best to “plan your pregnancy”. Why? The reason is that the vast majority of second-time mothers are still young and middle-aged, but there is no shortage of older middle-aged people. Some of them may already have medical conditions that increase the risk of pregnancy (called “comorbidities”) or have had pregnancy complications in previous pregnancies that can occur in the next pregnancy; or have had spontaneous abortion, early abortion, recurrent miscarriage, premature birth, or fetal developmental abnormalities in previous pregnancies. All of these conditions need to be evaluated well, so it is advisable to see your obstetrician 3-6 months before you are ready to get pregnant to give a factual report of your “history” so that your doctor can make a more accurate judgment of your risk of getting pregnant again. If you have a chronic medical condition, your obstetrician may also recommend that you see a specialist to assess your condition and whether it is suitable for pregnancy. Do you need ongoing treatment? Because pregnancy will certainly aggravate the existing disease or increase the burden and damage to the organs, those who do need treatment before pregnancy should maintain the minimum amount of treatment, in addition to changing the medication if necessary to reduce the risk of teratogenicity to the early embryo. If there is a family risk of inheritance, it is better to get a geneticist to determine the inheritance pattern and if prenatal diagnosis is done as early as possible in the next pregnancy. It is better to have a medical examination before pregnancy to know the functional status of one’s organs, especially thyroid function and screening for pathogens (rubella, cytomegalovirus, toxoplasmosis, etc.), and gynecological examination to exclude inflammatory diseases of the reproductive tract. The ability to conceive itself decreases with age, so knowing if the menstrual cycle is normal and monitoring ovulation if necessary will also contribute to the success of pregnancy. In addition, a healthy lifestyle and a positive attitude towards life are also very important. Both spouses should make efforts for it by living a regular life and avoiding bad habits (such as smoking, alcohol and drug abuse). It is essential to keep the weight within a reasonable range through a sensible and balanced diet and proper exercise.
