I just had my 5th child on June 13, 2007. I am still breastfeeding. With my last 3 children, my doctor has always given me the Errin Tablet for birth control. I know this is a progesterone only birth control pill. I have looked up info. on the web and one of the side effects is irregular bleeding. But I bleed a lot. On the web it seems like the irregular bleeding should be more like spotting and now full fledged bleeding all the time. But I do. Everytime I start bleeding, it's like I have a full period with the cramps, heavy bleeding, bloating, the whole 9 yards. Has anyone else taken this pill and if so, is this bleeding (in the amount) normal??? It's miserable to tell you the truth.
