The chance of conceiving during ovulation is generally between 60% and 70%, but if you have intercourse during ovulation, if you are overly nervous or have a serious habit of staying up late, if you are under stress, or if the quality of your sperm is not particularly good, such as smoking and drinking, the chance of conceiving during ovulation may be reduced. If the above mentioned external conditions are put aside, sperm quality is relatively good and there are no bad habits such as smoking and drinking, the chances of conception are very high, and the menstrual cycle is also very regular, which may also greatly increase the chances of conception. You can go to a pharmacy about 12 days after intercourse to buy an early pregnancy test to test whether there is a possibility of pregnancy. A negative test means that you are not pregnant, while a positive test means that you have conceived.
