Hi...I really need help!! I had sex on Feb 28 and haven't had sex since then...my period came on like it was suppose to in march to be exact it came on march 18 and went off on the 20. This month it was suppose to come on on the 15 but hasn't came on YET!! I did take 3 birth control pills at once 2 weeks ago and on top of that forgot to take two pills after that.. Still since then I haven't had any sex since Feb 28. Could this late period mean im pregnant or did I knock it off schedule when I took those 3 BC pills...I'm 7 days LATE!!!!
