Could I be pregnant??

Hey girls!

So I have been on the POP pill for almost 2 weeks. I switched right from a combo pill to this one. We had sex on the first day I started my POP. He did not finish inside of me.

Could I get pregnant from that?

Now last night, I’ve been on the pills for almost 2 weeks, we had sex and he did finish inside me?

Am I safe?
