6th september was my due date for sex. I engaged with my bf on 31 aug. He inserted tip of his penis but did not ejaculated. And my hymen is still intact. Still for safety i had i pil after 30 hrs. 6 was my due date but i had bleeding on 8th sept. Is this withdrawal bleeding or period and if its withdrawal bleeding then when will period come? Am i safe or pregnant? He just inserted tip and did not penetrate much and didn't ejaculate anywhere and as i said hymen in still intact.
