If I had sex on the 29th of February... no condom but no ejaculation inside of me, took the morning after pill within 10 hrs... and then got my period on the 5th... can I still get pregnant? How long do I have to wait before I can take a pregnancy test and be sure?

No one can tell you that, absolutely, except for your doctor. However, it sounds extreemly unlikely. Especially with the addition of the morning after pill and you getting your period.

Pregnancy is possible, but odds are quite low given the situation. You can try a test about two weeks afterwards, or even better, wait and see what happens when you would expect your next period.
