So me and my Bf, have had sex with a condom on, but the last few times it has been rough sex, the condom broke three times, and we didn't notice till after he pulled out before cuming. I go this Wednesday to get my implant (nexplanon) put in, and I'm afraid that I might be pregnate, its only been a week since they broke, and I had a pregnancy test done today 9/9/15 and it was negative.... Any suggestions or opinions?
