Switching pills will throw off your estrogen and progesterone and all the other lovely hormones in your system. Couple that w/this WOL and your bound to have a crazy cycle.

This WOL alone will cause some irregularities in your cycle at first. I believe it happens due to a release of estrogen into your system (as well as other hormones)-- it's stored in fat cells-- when you lose fat, they're released. They don't know their place yet b/c your body is still adjusting to this WOL. Once you've adjusted, things will return to normal. My first cycle was a week early and stayed for two even though I'm on Ortho Tri-Cyclen (and have been for a while).

Hang in there. However, if things don't improve, I'd place a *friendly* call to your doc to have him get your meds figured out.
