Pain on my period

Tiffany

So I’m currently my period. Day 3. I had a yeast infection before it started. I bought Monistat and it cleared up just a couple days before. But now I have horrible pain in my vaginal canal and around the opening. It’s worse when I wear tampons so I haven’t been using them. I’ve gone on the internet to look up a few different things but just can’t seem to figure out what it could be. Anyone experienced something similar? This is the first time I’ve ever been like this.
