Deeply personal question...tmi

Currently 7 weeks. I am having issues with discharge. It is so much more than before pregnant and even more now that I am using progesterone. I am constantly wet down there. It would just be irritating, but it is now getting to the point of painful. My skin is raw on my exterior labia from being damp all the time. I am using liners, changing regularly, changing underwear frequently, and using powder. Any other suggestions to help with the moisture? It seems to be like diaper rash.
