Hey everyone. I'm 33 weeks and 2 days, for the past week or so my baby has been getting the hiccups alot. Like 6-7 times a day lasting about 10-20 minutes at a time. This morning he has already had 2 episodes of the hiccups and I got a little worried after looking up on the Internet ( I know, big no no) and seeing that it could be his umbilical cord wrapped around his neck.
