my vagina is white inside, no discharge, just white. its never been white inside before. freaking me out! i have sex a few weeks ago used condom. but was after about precum so i took plan b a week ago (i was suppose to get my period that week). heard plan b can delay your period. afriad i still could be pregnant. and do i have a yeast infectoin? or why is my vagina white not now a week after taking plan b?
