Seasonal (Quasense, Jolessa) is a combined pill of estrogen and progestin preventing pregnancy. The main difference is that instead of taking active pills 21 day plus 7 days for the placebo pills you do take Seasonal continuesly for 84 days. In this way your uterine line is prevented from getting thick enough to produce a full menestrual cycle. You should know that you may get a breakthrough bleeding or start spotting because of low dose of the hormone estrogen. This is natural and will fade in time. Take 1 pill at the same time every day until you have taken all pills in the tablet dispenser. Avoid skipping Seasonale pills even if there is a bleeding or you feel sick to your stomach. Do not skip pills even if you don’t have sex often.
