Pregnant?

Hey all

I am 5 weeks late on my period.

I stopped taking birth control in late August and it took a month to come back (I didn't have a period while on my birth control). Since then I seem to have my period every 27 days. I haven't had mine since October 16-19.

I have had a large amount of stress with school, classes and my roommate being raped e weeks ago and dealing with that.

I'm so scared I'm pregnant but there are no other symptoms than just my late period. Help!
