Pregnancy acne treatment

I’ve never really been prone to acne. I woke up yesterday with 3 ready to pop zits on my face, then today with another one on the other side of my face. What’s bizarre to me is they’re like overnight zits. No sign of them, then boom! What’s your OB approved way to spot treat? Anything for prevention? I’m 14w3d expecting a boy if that makes a difference!! TIA!
