I am on ortho tri cyclin which is one of the most commonly used ones, and I have been losing weight just fine. I started protien power on April 15th and have lost 8 pounds already! When I first started this WOE, I did get my period out of the blue, which really shocked me because I have been on the pill for years and you get used to how it keeps you super regular. Did a search here for "periods" and found out that is pretty common for gals who just start low carbing.

I just love the pill actually, personally my fave birth control.
