Contact your doctor, that’s cause for concern
Definitely call the doctor asap clots of that size is what they look for when you are in the hospital
Yes I experienced one massive clot post partum and not much clotting after that. Just steady bleeding from the healing process
The biggest thing is to watch your bleeding, as long as you don’t have more bleeding (soaking through a pad every hour) then you should be okay!
You should contact your doctor. I was told with both my babies after I left the hospital I shouldn't have large blood clots golf ball size or larger and to contact them if I do. I think I had one large clot a couple weeks after I had my son I couldn't tell its actual size so I assumed I was fine. Which I was. Had no problems. I think if it's just one it may be okay. I know the concern is hemorrhage with losing big clots but there'd be a few large clots. It's pretty noticeable when that happens. Had that happen after my second one.
