Period

Sara
Okay so I started takeing birthcontrol and it I only took it like 3 times and I had to stop even though it regulates my period,  it made me have a a reaction, is it possible that  after I stopped takeing the birthcontrol tand after my last period I had intercourse I could become pregnant if I didn't use protection? And sperm went inside of me?  2 times and my period skipped when I was suppose to get it 2 times? And now it's late,
