It could be thrush with a heat rash on your inner thighs. Very common. Or vagatitis. Easily treated.

I would get it checked out. You want to get it cleared up so you can be comfortable - there is enough about pg that is uncomfortable without that as well!

Good luck!
yep, i was thinking thrush too..
I had very similar symptoms, and it nded up being thrush, caused from me using cheap brand soap to wash 'down there'.
I used the 6 day canasten vaginal cream, and only inserted the applicator in halfway. It cleared up in about 5 days or so.
