Well Has This Started With Your Pregnancy.. I'm not Going to Say Its Normal Because Its Constantly But I do Know That It Could Be whatever Kind Of Soap U Are Using.! U SHOULD Just Keep Up Some Cream for It
As long as there's no smell you should be fine....you could try vagisil to make sure everything is 100% clean down there. There's also no shame on just looking up things online
Don't use soap down there when cleaning, PH will balance itself! Use monistat 7 to get rid of the yeast infection (safe during pregnancy) and try to add yogurt and/or probiotics to your daily diet!
