Last month I had gotten my period from the 13th-18th then again from the 27th-Jan3rd which I had mentions to my doctors and he didn't fond it odd because my period is very irregular. Now on the 13th on this month I had sex with my boyfriend and we didn't use any protection which was fairly stupid on my part but anyways I haven't gotten my period for this month yet and I was wondering if I should just wait till I see my doctor Feb 13th and see if I get my period by then or if I should take an at home pregnancy test? I'm just very nervous and I don't know.
