Hello,
These bumps can be due to contact dermatitis, folliculitis or friction rub with clothes. Even yeast infection can cause such symptoms. If you are pregnant and having such symptoms then it needs evaluation and you need treatment as well as yeast infection can be passed on to the new born.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
you need to see a dr!!!! infections can cause preterm labour and you need to get the bumps swabbed! herpes can cause your baby to be blind if it gets in the eyes
