Sharp cramps since 4dpo

So I was wondering if anyone has experienced the same thing. I'm currently 10dpo and ever since 4dpo I've had small sharp cramps on either side of my pelvis. Kinda like both of my ovaries if that makes sense. This is the only time I've experienced this. Af due in 4 days but doesn't feel like normal af cramps

Anyone have any ideas 🤔
