Pregnancy

My period ended on the 7th of September and I had sex on the 19th! Was I ovulating on that day? And is it possible that I could be pregnant?

There are thousands of pregnancy questions on this website monthly - and the answer for every single one will remain the same:

No one can say yes or no. The only thing that can help you is taking a test, and looking out for the signs WITHOUT stressing out, as stress will delay your period.

..You could get pregnant at any time. Even if you are on your period, you can still get pregnant. Take a test.

take a test
next time it would be better to use a condom

If you have unprotected sex then you can always get pregnant. You could have been ovulating around the 14th to the 20th but there is no sure way to tell (though some women's discharge becomes milkier and more consistent when ovulating). Sperm can also live many days inside you which makes it even more likely to get pregnant. To avoid pregnancy use birth control.
