Im a first time mom too but my dr asked if i had any feelinga like that because babys are prone to hiccups from week 30 on. Talk to your dr about it that could be what it is.
It sounds like yur baby has the hiccups ! Id talk to your doctor about it tho just like the other girl above me reccomended
Ya, could be hiccups or if it's more from movement then that's normal too. Mine will sometimes jerk around and stuff like she's mad...kinda like a "get me outta here" jerking/kicking!
