Painful gas cramps

Ok ladies. I woke up this morning and thought my gallbladder was exploding or my appendix. Something. I couldn't move I had a sharp pain on my right side between my belly button and rib cage that would NOT let up no matter how I tried to move and only worsened with a deep breath. It finally passed just in time for the nurse to call back and tell me it's likely gas! How embarrassing I really thought something awful was happening. Anyone else have this? I know I'm not drinking enough water and I didn't think I was constipated but things are moving slightly slower then usual. Sorry I know TMI just need to know I'm not alone! I'm almost 16weeks.
