I think ringworm sya sis. Nagkaroon din ako nyan sa bandang singit before dahil sa laging basa undies/private area kakaihi and nairitate yung balat ko causing that infection. I suggest, inform mo OB mo to have a proper medication na safe sa inyo ni baby. And change undies na comfy, as much as possible yung maluwang atleast twice a day 🙂
PS: I used BL cream before, siguro twice a day ko sya nilalagyan and then lalagyan ko ng petroleum jelly after para kahit mabasa kiber lang. Dyan ako gumaling, kaso it's up to you kasi sabi may side effects ang BL na bad for baby pero sakin kasi hiyang ako dun and kung di ka naman maselan why not hehe Ask your OB na lang po para sure
