Oh! Thank God I'm not the only one dealing with this. I have pretty much the same side effects as everyone who has posted. I was on Seasonique for one cycle (which was fine, some light spotting) then the Pharm gave me Quasense. I'm about four weeks into the pack and I've noticed my clothes are fitting tighter and just thought it was holiday weight, but now I'm thinking its probably the pills! For the last week I've also had spotting and bleeding so much so that I can't have sex with my b/f either. Which is the reason I went on the pills in the first place -- more time for sex! I've had migraines in the past, but since going on Quasense I've had two in the past four weeks! I was worried I'm going to have a stroke or something! I called my doctor immediately after reading all the similar posts and had them call in a refill "brand necessary" for Seasonique. The nurse said that the bleeding and side effects were probably due to the Quasense, because even though Pharms prescribe the generic in place of the brand name, they are not exactly the same pharmacologically! If you are having problems with this pill, call your doctor and switch! No need to suffer or "stick it out" since everyone's body reacts differently to the pills. These are expensive and they should work like they are supposed to!
