When my little one pushed up it felt like I was punched in the stomach while she was streacging my uterus.
@op
It could be appendicitis or a gallbladder attack! Do you have any other symptoms or have you noticed anything particular that brings it on? I had gallstones in my last pregnancy and they are horrible. Upper right side of your stomach could easily be gallbladder or appendix.
Call your doctor/midwife first thing in the morning (or right now if your office has a 24 hour call line) and ask them. If it's your appendix you may need emergency surgery. If it's your gallbladder they can at least diagnose it and help you out a bit.
Yes. It must be heartburn. U need a medic for this
Probably just some heartburn
