I had the depo shot on a Tuesday(I was like two days late for my shot)I also had unprotected sex tgrew times within the 7 day window. However I HAD NO IDEA That I was suppose to use protection 7 days after the depo shot. So my question is can I be pregnant? I never have a cycle with depo but I've been vomiting, I'm nauseous off n on every day almost. Can I be pregnant or no ?
