Hi
I had bad pain all the way through my pregnancy.
At the begining I thought it was the endo but as the pregnancy continued it became worse and I was told that I had Irritable Uterus. Drs did alot of tests to try and find out what was causing it but everything came back normal. I also had bad constipation and I thought that was caused by the endo stretching around my bowel and irritating it.
I was told that it was safe to take panadole. Also it is safe to take metamucil while your pregnant.
Tell your Dr about it so that it is put on your record for future reference. Also keep a diary of the pain and give it a grade (eg between 1 & 10). This way you can show your Dr how bad & how often you get it.

Keep us updated on your progress.
Take care
Chris
