Is this a yeast infection?? I am ovulating (about to end) and I just had sex like a day or two ago and I was fine, I checked right now my cm because it was egg white now it looks like this mixed with egg white cm. Please help. Should I use monistat 7 again before it gets worse? The only thing itchy and bothering me is my clit because I have a really small cut on it. Other than that there's no other problem.
