Hello, I have been on the depo shot since 2010. That also means, I haven't had a single period since then. I just got off of the depo shot on March 19th. I started the pill form of birth control on March 24th. That being said, I have had unprotected sex at least 3 times in between these dates. Could I be pregnant or would the hormones still be in me? I also still haven't had my period since 2010.
