I've been tapering for about 2 months now and I'm down to 3 x 37.5 mg capsules, minus 54 beads. I'm not sure what to think about this... last menstrual cycle I had pretty bad cramps, but today out of nowhere I had completely debilitating cramps. I have endometriosis and had surgery to have it excised a few years ago. I'm worried it's coming back. I feel like I remember reading somewhere this is a rare side effect. Anyone know much about this or have any personal experience?
