I have a question as well I had sex 5 days before my expected period, I am now 2 days late, is this possible to be pregnant? I also am unsure because I have a didelphis uterus and am very unsure when I ovulate do to having not one but two uterus! I've been pregnant before so it's super hard to know after a week after having unprotected sex, and not being on any birth control. Please advice?
