Okay mommas, I have a question. I thought I started my first period, postpartum because I had pretty much completely stopped bleeding from birth. Problem is I've been bleeding for 11 days now. I read online that it's normal to have an abnormally long first period. How many of y'all have heard about this or experienced it? I haven't had the chance to talk to my doctor about it. Just wanna know if I should be concerned, because my husband and I also went ahead and did it, once I wasn't sore or bleeding anymore. Then this started a week later.
