Rhythmic thumping??? 🤔😮

33 weeks 5 days pregnant and feeling little rhytmic thumps in my lower pelvic area by my baby. This has been happening off and on for the last 2 weeks. Has anyone else felt this? From what I’ve googled 95% of articles and post that I’ve read says it’s the baby having hiccups. I’m hoping it’s that and not my son having seizures or something in my belly which he shouldn’t because he’s healthy....... but as a FTM EVERY little thing causes paranoia 😂.

I have an appointment with my OB on Jan 4th so I’m going to ask her then.
