Might sound weird but is it safe to sit on a heating pad while pregnant? Tmi: Due to some antibiotics I had to take I got a really bad yeast infection I got cream from the doctor for it but the last two days the opening of my vagina is very very swollen and painful especially sitting down. I assumed it was from the yeast infection and hope it gets better considering I take my last dose of antibiotics this morning. The heating pad feels very soothing on the low setting but I'm worried if its a problem for my baby? And if anyone has any suggestions for relief on this topic it would be appreciated, hope you all have a peaceful morning.
