You are getting close to the end. With everything that is going on in your body, growing baby, hormones, etc., you will feel growing discomfort.
You may want to check if you have a yeast infection, if your vagina is sore to the touch it could indicate something is going on. Yeast infections are COMMON during pregnancy and can be treated with some cream.
As babies get heavier, they feel like they are about to drop out of us. Perhaps you have 'dropped'? The baby is probably moving downwards at 35 weeks.
Be sure to tell these things to your doctor at your next weekly appointment and see what s/he says.
