Diarrhea-looking discharge (Warning TMI)

Halo

My period is expected to start in 5 day, about a week ago I started having brown discharge. The first day I didn’t notice, but it left a ring around my partners 🍆... the 2nd day nothing. The 3rd&4th day nothing, we didn’t have sex. The 5th day after we had sex there was a pile of chunky brown discharge all over him. It looked like diarrhea. If we were having 🍑 sex I’d think it was!! These last two days I’ve been spotting brown, which is normal..... but the other day was so weird. There was so much of it and it was so thick.

Also idk if this is relevant but I have HSV2, and last week I noticed a blister on my back. I took valacyclovir just in case it was a sign of herpes. You’re supposed to take it twice a day for a week but I kept forgetting to take it at night. So I took it only once a day, except today I’ve taken both 2. I don’t see anything about having discharge as a side effect of the medication but it didn’t start til after I took it from what I remember.

Has anyone had a similar thing happen?
