Nope... nada... At 35, grossly overweight and a heavy smoker, my gynae read me the riot act and refused to allow me the real pill any longer! She eventually relented and gave me a progesterone only one and one of the side effects is that you can have non stop period, and/or none, a mix of the two, or no change. I had no change for a few years, then they stopped. I freaked out, did tests every month, but now am relaxed about it! (Another fortune saved on protection!!)
