I performed my last intercourse on 30th april (although my partner used condom). Then I had my periods at 16th may which continued till 19th may and stopped like every month. Now suddenly i'm having my periods from 27th may evening with same menstrual symptoms like pain around breasts, pain in pelvic area and back and in head. And I am also taking homeopathy medicine for chronic pruritus vulvae and leukorrhea problem from many months now. Why is this periods happening. Can anyone pls tell me. Is this any sign of pregnancy? Though my partner used protection while performing intercourse. Can this be a sign of pregnancy or something else? Pls guide me pls.
