Possible, and extremely easy. Yes, that’s exactly what everyone who takes seasonale does 3 out of every 4 months. There’s no real evidence that there’s any “medical” need to have a period at all, and the period that women have on birth control is completely different from a “real” one anyway. I’m sure other users such as magsrags can expand on this. I should also add that sometimes some women will have a period anyway. It’s most likely that you’ll skip it, but you might have it regardless. That also happens to a lot of seasonale users.
