Welcome to HealthcareMagic. Pregnancy
occurs only during the time of ovulation. Ovulation is the release of a single, mature egg from a follicle that developed in the ovary and occurs on day 14 of a menstrual cycle.
You cannot get pregnant when you are having your periods and wearing clothes. for pregnancy, there should be ejaculation of sperms inside the vagina.
Hope it helps you. Regards.
