If you’re only 1 month postpartum it’s probably still from labor. When did you stop bleeding you think? Did you do anything active yesterday or harder than usual? If you get huge clumps then I’d definitely contact your doctor to see what they think.
It took me a month to stop bleeding because I was pp period bleeding then a I got my regular period on top of that. Diapered up till there’s no more blood that’s what I did.
I’m 12 weeks today and last night started cramping. I wish it would hurry up.
Some people restart their cycle quickly after delivery, some start later. It's all very normal, everyone's bodies are different.
