You probably had a reaction to the soap. I can't use bubble bath either. I get itchy and red. I say, switch soaps and you'll be fine.
I had put alot of soap on it and scrubbed down there so I am pretty sure soap got into there. The pain has seemed to have went away now. I have not had any pain since Monday morning
If you actually put the soapy rag up into your vagina, then yes the soap could easily be causing your pain, or the beginnings of a yeast infection. The vagina has a very sensitive ph balance and soaps really do a number on that. Even douching really isn't necessary as long as you bathe and shower regularly. Since it hasn't gotten any better, you may want to check in with your doctor just to make sure that's all that's going on.
Sometimes scented soaps give me a yeast infection. I only use unscented.
