Oh ya, me too. I had that. It was like my hormones and period came raging back. Now I'm older and am finding as my hormones shift, I have two days like this EVERY period. Ugh. I would give it a moth or cycle more to see if it normalizes and if it doesn't, set up a check by your doctor just to make sure all is well. I suspect it is and it is just hormones that increased your lining a bit more than usual post birth and seeing it expelled is a LOT. Been there. I was normal. good luck and congrats on your third baby. How old are your other two?
