YES.
simple answer YES!
Unless she came in contact with pre-cum that contained sperm, then no. She could be late for a lot of reasons. Her chance of being pregnant is VERY low.
periods are a sign that you are not pregnant, yet there is a very small chance you will be pregnant from your ex. it is probly going to be your boyfriends baby. congrats
If your period comes, it's unlikely that you're pregnant
Yes, yes you can.
You know that you are not pregnant .. if you had sex when you were un-fertile (but there is still a chance) and also .. You come on your period on the normal days you would have the other months
90% chance your pregnant
If she gets her period, then she isn't pregnant. If you have sex while she is on her period then there is a chance she will get pregnant.
Yes you can ovulate at any time.
Yes, there is a chance. Next time use some protection.
