I feel for you. I've had mine 27 days ago and dreading another one tomorrow. It was really bad and I left work and stayed home 2 days. I couldn't walk without feeling sick and the amount of blood that came out was scary (I didn't have that much during my both first or second labour). But to be honest there was nothing that big! I would suggest to go to a doctor ASAP, because a size of a golf ball is pretty big. Even after you have a baby they say nothing bigger than a toonie, but not that big. Stay strong and please take care of yourself!
