I had sex 7 days ago. During the make out session he used condom. But when it got filled with the sperms ejaculated he removed it. After sometime when both our private regions were dry he inserted his penis in for a while. Maybe for about 2-3 mins. And then he used the second condom for the rest of the making out session. He assured me that sperms did not enter that while. But I still didn't get my periods and it's the 36th day after my last menstural cycle.
