Fetal hiccups

R
I know that baby having the hiccups is very normal and a sign that they are practicing breathing but I feel them very frequently, at least once a day sometimes more and lasting for about 5 minutes. I read that after 32 weeks if you feel them a lot it can be a sign that the cord is pinched and baby is not getting enough oxygen. I have an appointment this week and am going to ask my doctor about it then but I'm curious if anyone else is feeling hiccups really frequently.
