I had my period the beginning of last nov and the end of nov. I normally have it the beginning of every month. Still have no sign. I've been nauseous in the mornings, lower back pain, slight cramping, heavy tender breast increasing in size , odd cravings to foods I never liked, and off sets to foods I use to love. I've had unprotected sex with partner for the past yr, and my mother informed me she had her period in the begging of both pregnancy. Should I be concerned for any reasons? Pregnancy or not!

It very well could be a pregnancy, no birth control is 100 percent, women using condoms and a pill, sometimes get pregnant.

So about two weeks after your period, or after missed period try a test.
