Im on my second month of my birth control pills.My first month i missed alot of pills. My second month i took my first two pills and on the night of my second pill i had unprotected sex. Could i be pregnant?

Anon - If you had a period you can't be pregnant. In terms of the changes you experienced they are likely related to not taking the pills as prescribed and your flow should go back to a more typical schedule when you take the pills as prescribed.
