Pregnancy occurs when a man and a woman have intercourse, with the man providing the sperm and the woman providing the egg. The sperm and the egg combine in the fallopian tube to form a fertilized egg, which further develops to form an embryo and lodges in the uterine cavity. Ovulation occurs 14 days before the next menstrual period, i.e. ovulation. The chances of getting pregnant are higher if you have sex five days before or after ovulation. You can’t get pregnant by picking at your vulva with your hands because there is no substantial sex. However, it is recommended that you do not pick the vulva with your hands, because picking the vulva with your hands can cause inflammation and infection of the vulva. Usually pay attention to keep the vulva clean, hygiene, wear breathable, absorbent cotton underwear, must change the bad habit of hand picking the vulva.
