I have been on seasonale for 1 month. At first it was great then during the 9th week I started spotting. This lasted for 7 days and then the blood clots started...HUGE blood clots. The bleeding was unbelievable. I was saturating a pad every hour or so....it was literally running down my legs. It was horrible. I also had uncontrollable weight gain and my bra doesn't even fit me anymore...none of my clothes fit me anymore. I've become very depressed...not as a side effect of the pill but as a side effect of the side effects. I stopped taking it. I'm still bleeding very heavy and I don't see an end in sight!....This is just my experience but I don't recommend Seasonale as all. Good luck to the rest of you, my heart goes out to you.
