Very true indeed. This is just my experience however. I had friends who bled for a long time and others who gained alot of weight on it. I was lucky to have no ill side effects, but this is just me. I am lucky to have had no ill side effects from either the first pill I was on, Depo and the current pill I am on. My advice would be this...if your mind is telling you more "no" than "yes" then go with the "no" and find another option.
