I had sex and he cum inside me last week on Tuesday. Not on birth control at the time. But this week later want get the depo shot. Am I still l protected or is there a chance I could possibly be pregnant?

I took the shot cause my husband would complain that I do not wanted to take the shots if accidentally become pregnant. I feel sore boobs like is hard to touch but hope is normal.

Thanks for the comments.

Update: yesterday i ate and when finished eating I threw up right away. Have sore boobs...maybe is a sign of early pregnancy. Anyone have a similar situation?
