Please Help.

Please no hate..
So last month I had an abortion. I am too young and it was not a good situation to bring a baby into. Now a month later I'm supposed to be expecting my period, and it hasn't come. And I've had sex of course. I know that my period could be late because of the abortion.. but I'm still wondering. So I guess my question is: can I actually be pregnant again? A month after I have the abortion?
