me and my boyfriend had sex 16 days after i got my depo shot we used a condom which didnt break but when he pulled out to finish he took the condom off and some a few drops got on top of my pussy. (kinda on the wet part). i got done ovulating completely 2 days ago. what are the odds? should i take plan b? and if i should take plan b is it ok to take in 2 times in a month?
