Tmi!!!

Okay. So ladies please no judgement here... I went swimming and wore my wet bottoms for a good while after I got out, needless to say I got chapped like no other! I now have these bumps coming up... They are very itchy... I have one like on the top on my butthole and some on my lips Down low... Is it from being chaped or could it be an outside yeast infection or something worse?? I'm 19 weeks and I've called my doctor have an appointment in a few days just wanted to get some opnioms before going in!!
