TMI what is this? Rash?

So I have these spots that HURT in the area between my vagina and anus. 
I'm 32 weeks pregnant. 
I have had herpes before but not in that spot
Yesterday my washer started leaking and I ended up cleaning bleach water everywhere. So it potentially could've gotten on me. Or I could've touched there accidentally. 
I know I scratch in my sleep. But it doesn't look like scratches. 
I used baby powder down there for the first time yesterday. 
I also shaved yesterday. 
So there's at least 5 possibilities. Just wanted opinions:
I tried to get as little of anything else and as much of the "rash" as I could. Just want opinions. Thank you.
