Your period could totally be late due to stress. Since you had your November period, you should be in the clear. But the only way to know for sure is to do a home pregnancy test. The peace of mind will be worth the $15.00. Good luck! Keep us posted!
well my period was early this month!!!
If your period came at your usual time, and it was your usual flow then you are probably not pregnant.
It is possible to still have a period though in early pregnancy, so do yourself and your boyfriend a favour and get a home pregnancy test done!!!!
Also I am sure you know, but you need to use some form of birth control, boyfriends come and go, but a baby is for life.
