Heres what has happened in the past month with me and my girlfriend:
A week after her period, I cleaned some sperm off of myself with a towel, then she used it unknowingly on herself to clean her vagina.
Next week we had unprotected sex (i know bad idea) but i wasn't too worried because it was only for literally 30 seconds.
Then two weeks later, when her period was due (the 3-5) it didn't come, and we started to worry.
On the 6th (after she was at least a day late at the minimum) we had been doin it for a while, and the condom broke. It was a spermicidal/lubricated condom, but it had gotten dry since we were in a vehical.
I had her take two tests in the past week, and they were both negative, AND she just started her period about 20minutes ago. Am I safe now that she started and those tests were negative? Or should I still be worried about the broken condom because it was after she was late and we wouldn't know until IF she misses her next period?
