Yes, there is a high chance that she could be pregnant
It is possible, but extremely unlikely.
This is unlikely, although it could be possible depending on when you ovulated.
Yes if after your period but if seven days before your period you will not become pregnant...
If there was unprotected intercourse in there somewhere then yes.
VERY. Its happened to me too many times.
If you've had unprotected intercourse, yes. Ask your mom so you can take a test. This is not something you want to drag out on and have no options in the end. 11yo have become pregnant before.
No, you don't have to get your period to get pregnant. Menstruation occurs after ovulation, if the egg is not fertilized. Thus you could get pregnant before you ever start menstruating as you could be fertile before then.
if you had unprotected sex , yes
