Today I am 6 weeks and 4 days post childbirth. I started the mini pill exactly two weeks ago. I am breast feeding but only half of the time. The rest of the time we use formula. I haven't had post partum bleeding in over three weeks. I have however spotted lightly off and on since starting the new birth control. Today I started bleeding in what I would consider a medium to light day on a period with very small clots. Does that sound like a period even though I'm breast feeding or should I call the doctor?
