I had gotten my Depo shot on July 25th Monday , and I had unprotected sex on the 30th. 6 days on the Depo shot and I was supposed to wait 7 days after the shot . So on the 1st of August 3ish days later I took plan b. Just to be safe .but now I had sex again on the same day of taking Plan B ! Am I safe ? Or should I take Plan B again .
