Desperate for help... my boyfriend and I had sex on Nov. 6th and I get my period on the 23rd which I am 3 days late now. I took two pregnancy test before I missed my period and both were negative. I have cramping and lower back pain but no period. Could I be pregnant? Although I have no symptoms of pregnancy but I do have this weird feelings on my teeth like I have been chewing on foil. Should I take another test or wait it out longer?

Give it another week and see if your period is just late... which can happen sometimes. Test again at that time if still no period.

You might have walked yourself into a viscous circle.
You're stressed about not getting your period, this stress is delaying your period. This makes you more stressed about getting your period, this stress delays your period even more.

But I stress a lot and I never skip.. . I am a full time student and the boyfriend stresses me out and I never miss.
