V.L.
I had terrible pain also in my side. They too ran a test to find out if it was the gall bladder. Turns out it was okay. Got diagnosed with Phrenic(sp) nerve pain. Nerve that runs along diaphragm gets irritated due to extra fluid and Gas trapped in your system. Very common during pregnancy. I did not experience the pain any longer once I delivered. I hope it is not your gall bladder and just something that goes away!!!
