I'm trying to figure out if this is normal. This time I lay on my right side with my right knee up as hopinso suggested. This time I had a sharp pain sort of under my left ribcage. Is this where the gallbladder is? Is this normal to have some pain when the gallbladder starts sqeezing out bile? It subsided just as soon as I turned over on my back. (I stayed on my side for 25 minutes). I don't have any known gallbladder problems. I'm doing this hoping to help my PCOS and infertility. I had no pain during my first flush, but I lay on my back that time.
