So I had unprotected sex with a guy and about two weeks later I had what it seemed to me like a period it was just like a period and lasted just like a period . But it did start a whole week before my period usually starts. But if I am pregnant today is I am 4w1d the last week I have been experiencing sore breasts ... I can smell something far afar I wake up at like 2 in the morning everyday super hungry and I have to pee every 3 minutes . I don’t know what’s going on . ? Could I possibly be expecting?
