please don't judge. out of intense love, me and my boyfriend turned to had sex 7 days after my period started, and there's still a little amount of blood in me when we did it. When we have sex, he pulled back right away and then he ejaculate for about 1 minute before his sperm come out and we didn't had sex again (we stop already after he ejaculated). after 3 days, i suffered from urinary tract infection and cure it with antibiotics for about a week. as i calculated and use 28 days calculation in menstruation, my period supposed to be started last feb 16, because my last period was jan. 19. but as of today, i am still having no period (5 days late) but i feel some PMS going on with me and there's some rumbling in my stomach and abdomen like there are worms crawling. should i get worried? is it possible that i am pregnant? a little answer can help because i'm stressing a lot lately. thank you very much!
