Can I get pregnant?

So I was getting it on with my bf and we didn’t use a condom 🤦🏼‍♀️... I was on top and he lifted me up when he cummed and I got right off of him... most of the cum was on his dick and on him... so should I be worried? I’m fertile according to glow

Update: I’ve taken plan b 2 times in my life and I’m not taking it again...
