I'm 3 days late on my period I've been experiencing a few cramps as if my period is on but it's not on. And last week my boobs were hurting and seem like they are bigger so I had to get a bigger bra. Im not sure when I should take a pregnancy test. But for anyone who has been pregnant before can you tell me some more signs or symptoms in order to know if I'm pregnant or not and as to when I need to take a pregnancy test
