I have had this since yesterday. The day before yesterday was the last day of my period. It is embarrassing! Please help!

Just a guess possibly thrush

We don't guess here. No one can diagnose you over the internet, and on this site we will not give you a diagnosis, we care too much about your health to do that.

A yeast infection is a possibility, but it's not the only option. The only way to know for sure is to see your doctor, and that's really the only answer we can give you.

Good luck.

That's an infection that you have got in that part of your body. Immediately consult your doctor for this trouble or else it can give you more problem.
