I had unprotected sex on tuesday i took morning after pill on the wednesday at my local gp. they give me my depo-provera injection first. will the m.a.p work?

Very Likely to work!: You took the morning after pill during the recommended time. Its very likely to work. No method of contraception is 100% foolproof so you may want to take a home pregnancy test at least 2 weeks after the m.A.P. The Depo-Provera doesn't work immediately so you should use condoms also for the next several weeks.

Decreases risk : You used emergency contraception correctly. It also good that you started a better form of birth control too with depo. Emergency birth control decreased the risk of pregnancy.
