S.H.
V.,
In my first pregnancy I came down with HELLP Syndrome at about 29 or 30 weeks. They at first thought I had the flu that was going around at the time, then thought it was my gallbladder. Ultra sounds showed it was not that. I do not want to scare you, but ended up going to the emergency room because the pain was so bad and had to have an emergency C-section.
The HELLP stands for High Enzymes Low Liver Platelets. It is not very common and a lot of the characteristics are similar to preclampsia. But is more serious.
Talk to you Dr and see what their thoughts are about it. I knew nothing about it when diagnosed. For once in my life, Ignorance was bliss...
I hope you are able to find out what is causing the pain and everything ends with a happy, healthy baby and mom! Take care.
