I came off depo january 22nd 2016, had unprotected 28th and february 7th. chances of being pregnant?

Depoprovera: If your Depoprovera expired on January 22nd and then you had sex afterwards then pregnancy is possible. IF you miss your next period then check a pregnancy test. If you do not want to be pregnant consider restarting birth control

Not likely: Each Depo-provera injection is meant to prevent pregnancy for up to 12 weeks. The answer depends on when you had your last injection (we may be talking about different things when you mention you came off it, so I’d rather be safe rather than sorry). If January 28th and February 7th fall in that 12 week range since your injection, then it’s unlikely you’ll get pregnant.
