diclegis

Does anyone on here take diclegis for nausea? I take it currently have been sense 7 weeks I'm now 14 I take 2 at night and 1 in the morning, I ran out last night so didn't have any to take I woke up this morning throwing up my stomach acid (yellow and burned tasted TERRIBLE) my stomach feels like there's slight cramps, I feel very nauseated and ate some toast but still feel weird. I'm scared my baby girl isn't okay, just wanted to see if you think maybe this is withdrawal of the pill? my body is so used to taking it now it's acting weird without it?
