Every month it's something new. I finished my 10 days of progesterone last Tuesday. Today is my 4th day of having a headache, my chin is breaking out terribly, and I'm a little bit ragey. My bleed starts before I finish the progesterone, so there's no pre- to this if it's PMS. Is anyone else affected by the progesterone withdrawal like this? Even towards the end of your bleed?
