Odd symptoms and discharge

I had a rough week. I’m experiencing some yellow/green discharge. To give some backstory…..

My period started last Sunday. I also had sex. The following Monday I woke up fine for work but around noon, I started having chills and had a slight fever that lasted til Tuesday morning. I chunked it up to my recent work travels and a few of my coworkers have been getting sick.

I used an always period panty and all of a sudden my vulva got swollen and itchy. Figured it was an allergic reaction so I took a Benadryl and stopped using them and went back to pads/tampons.

Now, my period stopped but i’m seeing this discharge and I’m concerned because i’ve never experienced this before. It has no odor.

Has anyone had this experience?
