do I talk to my OB?

Nancy

For the last couple months, I've had a reoccurring large pimple type thing that comes and is on the inside of my lower butt cheek, so it rubs when I walk, it's very hard at the moment and impossible to pop because my butt is very "squishy" I guess you could say, it's very big in general. I'm 25 weeks pregnant so I don't know if this is something I should ask my OB about or go to a different doctor for it??
