Yesterday my girlfriend had finished her period, this lasted 5 days and it is irregular. We decided to have protected sex using a condom, had sex and condom did not break, then I went to the bathroom and wash my penis and urinate. Passed 2 hours and returned to have sex, it should be noted that this time the condom broke but i didn't ejaculated and we didn't last long time having sex with a broken condom ... I know that the pre-seminal fluid is used to prepare the right environment in the urethra to release sperm, but I think even I urinated some sperm content could remain in the urethra and therefore this can impregnate her. My questions are: Can get pregnant just after finishing period? Could some sperm remained contained in pre-seminal fluid?
