Could I be pregnant?

You could be pregnant, I got off birth control in August I got my period early September and I'm now 4weeks.

You could be pregnant but also your body could be regulating after birth control. Irregular cycles after stopping birth control is common

My dr told me you're most fertile after stopping BC. Take a test!

Take a test for sure. When I got off birth control to start trying for my first I never got my period but I wasn’t pregnant right away. My timeline was stopping my pills mid-May, no period in June or July and then August 2nd I had a positive pregnancy test and had my baby April 7th. My doctor estimated my conception date as July 18th from a 6 week ultrasound since I didn’t have an accurate LMP to go off of. So you could still be regulating hormones and that’s why you haven’t gotten a period or you could be preggo but the only way to know is to test. Good luck!!
