Ass acne

So I'm 33 weeks pregnant right now and my ass has decided to have a major breakout. I DO wash my ass (when I shower, which is daily) so I know its not dirty and we haven't changed laundry detergents so it can't be that.... I've never had this problem before so I'm at a total loss as to why my ass is having such a break out.

I've had a small breakout on my face but that's nothing unusual so I don't think its connected.

Any ideas?
