Contractions or BH?

So last night I was getting not so painful cramping off & on, I wasn’t timing because I’m not sure what I was experiencing. But I’d say they lasted idk 20-30 seconds off & on. Not sure how often, I didn’t time 🤣

The cramping wrapped around my lower belly & back, it felt like tightening period cramps or something. I didn’t touch to feel my belly, but when I’d try & move it did feel tight & heavy. It was 12am I was just laying in bed. I’m 39 weeks on Monday. Been having a ton of lightning crotch yesterday & baby has dropped. Been feeling like theres a bowling ball between my legs lately lol.
