Nobody on here can tell you whether or not you're pregnant.... I can only say that if you've had sex then there's a possibility. Pick up a hpt and find out!

Good luck to you!

Welcome to my life! I went off the pill, got my period right away (in july, same as you) and then that was it. I am ttc so I am testing every few weeks or so just to see if I am. And i'm "acting pregnanct"..Not drinking or smoking and trying to be healthy.
I just talked to my obgyn and she says it's totally normal to take upt to 4-5 months to get your period back again. She also told me if I don't get it in a month that they will do a pregnancy test and as long as it's neg. Give me progesterone to jump start my period.
So i'm in the same boat. It's sucha pain!!!
