Umm, Ihad intercourse two weeks ago and my vagina been acting funny lately.At first I thought I had a yeast infection because it was itching and discharge was thick but After a few days from inserting the cream, my vagina had an awful fishy smell. My discharge looks like strawberry milkshake. Im wondering if i have to change my diet or if its an infection , Helpp??. P.S. I have an IUD.
