Portia
"I've been on Portia for over a year and can't complain.  I have always had terrible cramps, on the verge of endometriosis, and this is the first birth control of several I've been on that has actually reduced the cramps - and quite significantly.  I don't really have problems with PMS at all, but have noticed a lower sex drive.  But my periods last 2 days now, and are pretty light, so it's treated me well."
