Postpartum bleeding


Sorry if this is in a wrong section but if any of you mommas can answer a question.

My baby is 4 months, I have had what I thought I guess are three periods since I had the baby, heavy bleeding. . I was bleeding for few weeks right after the baby, it stopped, then my periods came somewhat regularly, and still heavy bleeding.

Now back to this last month, I have been bleeding for 4 weeks straight, it’s not like period, its somewhat light spotting. Enough to use a liner and not enough for a tampon, but it’s every day. I also started taking birth control somewhere around the time spotting started so I haven’t finished pack to have my period.

I am just curious have any of you experiences this? I am getting a little nervous that something is wrong.
