So... I'm exclusively breastfeeding and I got my first period 4 weeks after delivery. It lasted for about a week and then I got it again a week later. Long story short, I've been bleeding for 3 weeks now! It's not a heavy flow, but it's not going away.

During my post partum visit to the obgyn he said that irregular bleeding was normal, but this doesn't seem so to me. I've been feeling a little weaker the past few days and I'm concerned I might be anemic.

I will call the doctor tomorrow but I'm very worried now. Hoping everything is ok.
