Birth control and 2 periods?...

Ch

So I’m on birth control for now after I had my first babygirl on July 29th. But I’ve had my first period, stopped bleeding for a week, and had another period in the same month?! It’s still happening, it’s been two weeks I’ve had this second period.

I’m ALWAYS on time with my birth control, and my placebo (sugar pill) week is next week.

Has this happened to anyone? Is this normal? I go to see my doctor Friday about it.
