Hi queenofkings,You should not be struggling with this on your own. You are pregnant, which means that you need to let your doctor know exactly what's going on and ask what you can and can't take to help yourself. As Erica said, there are many things that are okay to take while pregnant. Please call your doctor and ask him/her what is recommended for the problems you're having. Heartburn during pregnancy is extremely common, so your doctor won't be surprised.
It's obvious that you're in a lot of discomfort. Avoid GERD triggers (Erica has listed some), and please call your OB/GYN office for guidance. You've described the pain you're in very clearly...be sure to do the same when talking to your doctor. There is help out there for you.
Hang in there!
