Weird ??

So I'm 9dpo and I had a bit of cramping like 4-5dpo. I had just got off bc and only had one period so I kind of thought I was getting AF since I've heard periods can be really irregular when you get off bc. Anyways the past few days I've been having weird cramps?? Like it kind of feels like I need to have a bm even after I already have, but I really only feel it when I'm sitting or laying down. Anyone else have this before ??
