Not endo related for me I don't think... but I sometimes get dreadful O pain down into my bowels. When not TTCing I take panadol/nurofen.. whatever is on hand! cos it just hurts so much. I try not to take anything when TTC tho and know that I just have to wait it out. Sometimes I'm doubled over on the loo not knowing whether it's my bowel or not!

Would love for it to be O for you! *hugs*
