Anyone on The Patch ?!

I recently started the patch and I'm on my week off . Friday is my day change and I haven't had my period yet but only this weird discharge that comes when your cycle is going off . Kinda brown and milky ( been tested for stds and negative on that note ) . Just been having PMS symptoms ... Cramping , breast tenderness , cravings etc. My question is for anyone who uses/used the patch how did it go for you and how did our body react to it ?
