How high is the pregnancy rate? How many pregnancies are born?

The most direct way to improve the chances of pregnancy is to use ovulation for cohabitation, which allows sperm and eggs to combine better, thus forming fertilized eggs and entering the uterus. Under normal menstrual cycles, ovulation is generally pushed 14 days before the next menstrual cycle, or tested with ovulation test paper. The baby will be born about 280 days after successful pregnancy. The pregnancy cycle is 40 weeks. However, some babies may be born early or late. For premature babies, some survival rates are not high and their physique is relatively poor.
