My first period or 2 after birth were always heavier than normal.
I was told to only worry if I have blood clots the size of a golf ball during pp I bleed heavy it will take a bit to stop an your monthly the first month probably will be heavy
I was bleeding for about 3 1/2 weeks, and I had a c-section I was always spotting though never bleeding. And they told me if I see a clot too go to the hospital
