1st period after baby

How was your first period after you had the baby? Had my son in February got my first period in April, and it was sooo bad like I was literally changing the pad every couple of mins. It was do bad with A LOT of clots that I thought something was wrong. I went to the hospital, they did tests and an ultrasound of my vagina and uterus and everything came back normal. First time mom and everything worries me lol
