Hiccups you would feel higher than your bikini line. I think i know what youre talking about, i had those same spasms the last few weeks of my pregnancy with my son. Doctor said it was my cervix twitching and its normal. Im guessing its your cervix prepping itself for dilation.
Doctor said just contractions. .. and streching..
Then I dont know. Sorry. My second is just starting to get hiccups. Only started yesterday and I'm 36 weeks along.
She does get hiccups a lot but they are not the same feeling. This feels like when you get a muscle spasm, like the twitching. . It's hard to explain. :(
Could be baby hiccups. My first had them all the time. If it seems like it is at regular intervals that is what I would think they are.
