Pregnant possibilities?

Liz

My bf and I had sex yesterday and the day before. Both in which he came in me. I just started a new bc (combination pill) after getting off of the mini pill. I started my pill on the first day of my period which I heard allowed it to be immediately effective. We had sex on Saturday and Sunday, I started the pill the Monday before. I was on the last 2 days of my period as well. I’m just a little worried since I had just started a new pill.
