thank you for your query.
If you have had vaginal intercourse, and have skipped your period, then pregnancy
is definitely a possibility.
In future, please ensure that you have protected intercourse
would not work for you.
Please take a pregnancy test.
If positive, consult your Gynecologist regarding an abortion
If negative, then wait for a few days, and if you still do not have your period, you still need to see a doctor for medication for withdrawal bleeding.
Do not self medicate yourself.
