ok here goes. i am 30 weeks pregnant and nipples have been doing normal weird preg things like getting darker and bumpier. But now I am noticing them getting very itchy and on the tips I am getting very small like crusty yellow 'sap'?!. When I remove them (very carefully) it stops the itching. what is it??? also the surrounding nipples have suddenly got a bit white flaky. I have regualr showers without soap to its not irratating/causing it. Am i just a freak or is anyone else getting this????
