So I had sex on the 14th day of my cycle (and on the 14th of this month), it was unprotected and he finished inside of me. Bigger problem is I didn't take my pill for the next 4 days because I forgot, I get my periods early if I don't take it right. So now I'm worried, can I still possibly get pregnant? Its not like my usual periods. Its a lot more mild (almost nothing)

What do I do?
