I've always gotten those. It's just your diaphragm having a little spasm. Mine always does it when I take a big drink. It's normal to have more hiccups when you're pregnant, at least it's just one and not an hours worth lol
Lucky. I have always gotten the hickups for hours at a time and for some odd reason the hickups make me giggle which makes my hickups worse lol
Pregnancy uterine growth pushes on your diaphragm and can cause random spasms and hiccups. Very normal. Some women notice them more than others.
