Light cramping since ovulation...what could it be? 8dpo

So I've been getting light cramping since ovulation day and I'm 8dpo now. They got a bit worse last weekend but are a bit better now. They're still hanging around though and I'm starting to worry what it could be. It kind of feels like af cramps but it's more steady and my AF cramps kind of come and go. This is just like a steady feeling though. Sex doesn't make it better or worse and they're nowhere near as painful as AF although they get much worse when I have to pee. So weird. AF is due next Saturday. Anyone else ever get this?
