I know im not pregnant yet, at least it wont show that i am on a home pregnancy test. Anyways I had my first and only depo shot in july. I never went for my second one and i started getting my periods in November.. I had unprotected sex with my boyfriend a few days ago. The 4th to be exact. Could O still be protected by the depo shot or not at all? & How long until I can take a pregnancy test? Im going for a check up in about 2 weeks but im so impatient im just trying to get as much information as i can.
