Breastfeeding and the mini pill

I'm breastfeeding so I'm on the mini pill.  I've been lightly bleeding for a week and half. It all began a week after I started the pills.  Anyone else experience this? I'm so annoyed I'm ready to just quit taking them. Unfortunately I don't like any of the other BC options avail for breastfeeding women but getting pregnant again seems awful. Anyone else experiencing weird symptoms with mini pill? Should I just buck up and try to ride it out? After labor and delivery and post partum bleeding and dealing with breastfeeding, I'm so over more bleeding. :/
