The fact that you may get pregnant before intercourse with a white belt pulling is just a general inference that conception is a more complicated process and whether or not you can get pregnant successfully varies from person to person.
If you have intercourse before the leukorrhea, the sperm can survive in the woman’s body for 48 to 72 hours after intercourse, during which time the ovaries discharge the mature follicles, and then there will be a possibility of pregnancy. Whether or not you can get pregnant successfully varies from person to person. Conception is a more complicated process, and although the ovaries ovulate, a woman’s uterine lining is too thin, the fallopian tubes are blocked, and the quality of the sperm is abnormal, all of which may affect a woman’s ability to get pregnant. If you want to increase the chances of intercourse, wait until the follicle is discharged, and then have intercourse. If you don’t want a woman to have an unwanted pregnancy, try to do a good job of contraception.
