My DH is a biomedical engineer and works with biomedical waste, so he's seen much worse.
The only thing that freaked him out was the idea of cutting the cord for some reason (I think he was more afraid of somehow screwing it up than he was grossed out by it), and he swore he wouldn't do it... but when the moment came, he did it.
I will be mad at him until the day I die about what he did AFTER the delivery, though. He went home to let the dogs out a few hours after my LO was born and he never came back. I called him ALL DAY and his phone just rang and rang. I sent him a million texts. I hadn't slept in 30 hours, I just spent 18 hours in labour, my LO would not be put down, and I was a crying, miserable mess. He FINALLY showed up like 12 hours later, said he passed out on the couch with the dog's leashes in his hands and everything. I don't really believe him, I think he turned his phone on silent and slept the day away. 😠
Anyway...
Yeah, the post-partum bleeding is nuts. I had to have my sheets changed every hour because every time I moved I just exploded blood straight through my pads and underwear all over the bed. I passed HUGE clots as well, even over a week after giving birth. I went to the bathroom once at home and passed a clot the size of a baseball, it felt like I was giving birth to a steak.
