Hi, welcome to BB and congrats on your pregnancy.
DD used to get hiccups all the time, when i was in bed at night , she would wake me up with them, if i got up and walked around they seemed to stop. she probably got them three times a day sometimes. only lasted about ten mins and they would stop. right at the end my DH could put his hand on my tummy and feel her hiccuping too!
I mentioned it to my doc and she said it was nothing to worry about, i think she actually laughed at me for asking but like sloane said, its better to ask someone you trust and who knows (ie. your doc) to put any worries out of your mind!!
DD still hiccups quite alot now, so i think shes just prone to it.
