If a woman wants to get pregnant, she should first regulate her body, strengthen her physique to ensure that her ovulation cycle is normal and the quality of her egg cells will be relatively good, and she also needs to grasp the timing of conception. After a woman has sex with a man without contraception, the man’s semen will enter the woman’s vagina. The sperm in the semen then travels to the woman’s fallopian tubes where it combines with the egg to form a fertilized egg. The fertilized egg moves into the uterine cavity, lodges in the uterine lining and continues to develop before the woman can successfully conceive. In order to have a healthy baby, it is important to have a healthy body to prepare for pregnancy. The overall process of conception is complex and requires a number of key conditions to be present at the same time, so it is advisable to visit the hospital and undergo the relevant tests first during the preparatory period. For example, blood test to find out whether there is anemia and blood disease; urine test to find out whether there is kidney disease; leukorrhea test to find out whether there is vaginitis and any disease that may cause intrauterine or intrauterine infection of the fetus; ultrasound to find out the development of ovaries and uterus; and cervical cancer screening, infectious disease test and chromosome test. In addition, it is necessary to grasp the timing of pregnancy. From a medical point of view, it is generally believed that 25-35 years of age is the most appropriate to get pregnant, under the age of 18 and more than 35 years of age to give birth is known as high-risk pregnancy, when the risk of pregnancy increases. At the same time, since a woman’s probability of conception is higher during ovulation, if you have a fertility program, you can arrange intercourse during ovulation. Lying flat on your back with proper padding after intercourse can increase the chances of conception. Finally, from the eugenic point of view, it is recommended that a woman should focus on ensuring a healthy lifestyle before pregnancy, such as quitting smoking, taking drugs that are teratogenic to the fetus, not staying up all night, and keeping a happy mood.
