Yes it is possible from his pre-cum to get pregnant. He does not need to ejaculate.
Probably not. If you had your period, then you are most likely not pregnant.
If your period is heavy then it's unlikely that you're pregnant
If you're a guy, nothing. If you're a girl you may become pregnant, but it doesn't take three days.
No you are not pregnant because you have had a period. Next time you may not be so lucky, carry condoms!
Yeah, you can get pregnant at anytime, sperm lives inside you for a few days.
any time you have sex, there is a chance to get pregnant, there is no 100% guarantee. however, as long as you are taking the pills correctly, and he is using the condom correctly, no matter if he cums more than once in it, there is a very low chance of pregancy, and i wouldn't worry about it
If your period was heavy or like usual then its not likely that you are pregnant.
No, if you were pregnant you wouldn't have one at all.
