Its prolli a yeast infection my dox got me med for it
you also may have thrush which is extremely common in pregnancy :)
Lol pregnancy is a wonderful thing , but it can cause alot or weird syptoms that are different for everyone. Perhaphs the extra blood flow down there is causing you to be a little more sentative. Also any changes in fabrics or under wear being to tight can cause itchiness. If you shave that are it might become irritated and itchy. I guess it could be for a million different reasons. Anyway if it continues or appears to get worse I would let your doctor know. Congrats on the pregnancy!
