I don't think that it is safe right before your period. There isn't really a safe time to have sex because the safest time is a few days before the egg is in ovulation, But since no one knows when that time will be, it's not really that safe. But you can take your chances if you have a regular occurring period.
It could be that she is pregnant. Anytime you have unprotected sex, the woman could become pregnant. You are wise to be concerned. Pre-cum is very potent. If you are worried, buy her a pregnancy test as soon as the first day of her missed period.
Just before your period you are at your most fertile
Yes! With octuplets!
yes
No because when you have it it lets out eggs and if you dont have it quite yet you could not get pregnant
"If you have unprotected sex 11 days before you were due your period could you get pregnant" Yes. because the womb has not bled out yet, and it still open. I don't think you can get pregnant and get your period at the same time, If that happened, the baby died. and you need to see a doctor. Are you under-age? The way to tell if your pregnant, Is if you missed your period, Irregularity does not mean you are having a child.
YES.
No
yes you can
You're not very fertile during you period. But isn't safe to say the possibility of getting pregnant is 0%. If he didnt ejaculate you shouldn't really worry. All you can do is wait and see. I think you should be more worried about STD. Use protection.
no you can not get pregnant through oral sex. There may have been some sperm left on his penis when you had unprotected sex though. Theres still a possibility.
Yes you can.
