If you have unprotected sex 11 days before you were due your period could you get pregnant and then get your period when they were due 11 days after having unprotected sex?
"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.
