Placenta expulsion 5 1/2 weeks later I was told I was miscarrying

Chazi
So, I was told I was miscarrying at the end of January when I went for an ultrasound after I had some painless light bleeding. They told me to wait. The bleeding stopped after a few days and I thought that was it, even thou it was totally painless. I thought I was lucky. Yesterday I thought I'd finally got my period back but Today, 6 weeks later, I started having some bad cramping and heavy bleeding. They got more and more intense and frequent and I realised those were contractions. After 6 extremely painful  hours all I could do was to push and suddenly this thing comes out and I'm still in total shock. Why did it happen so late? Has this happened to anybody? Gonna go to the hospital tomorrow morning as I feel fine now but I am worried.
