Thanks for using the forum.
I can't tell you when to expect your period. It should resume once your hormone levels return to normal.
If you have been sexually active, pregnancy is always possible.You do not have to restart your period before it is possible to get pregnant. If you ovulated 12-24 hours before engaging in unprotected sex, then you could be pregnant.
If your period does not resume in the next couple of weeks, I would recommend speaking with your doctor or trying a home pregnancy test.
Good luck.
