Frequent fetal hiccups for 10 minutes at a time?

I’m 33 weeks and my baby has had a major increase in hiccuping. He had the hiccups 5 times in the past 24 hours for approximately 10 minutes at a time. I saw a post on here of someone saying their baby had the hiccups 10-15 minutes at a time and it ended up being the cord wrapped around her neck and being compressed. Of course I am in full panic mode now.

Just wondering if this is something to be concerned about or not. My doctor’s office is closed until Tuesday with no on call. My only option is to go to emerge and not sure if this is cause for a visit or not.
