I'm 18 weeks pregnant and have been having some problems with acid indigestion and nausea which had been improving. But last night, and one night last week, I woke up in the middle of the night with an intense burning pain in my stomach. It was bad enough that it had me rolling around on the bed. The pain was in my actual stomach, not lower down or anything. After a few minutes I needed to be sick so got up. It was so acidic that my throat feels burned today and didn't appear to have any food in it After I'd been sick I felt better, although my throat is still very sore. Anyone any ideas on what could be causing it? The first time I thought maybe a virus but it seems to be repeating at random. TIA
