first time mc. and feeling so alone

Thursday I was told at my first us that I had a sac but it was empty..... they scheduled another u.s. for Tuesday but said to expect a possible mc.... yesterday the bleeding started and today the cramps started. while they are tolerable it almost feels like the early stages of labour from my first child. how long should I expect the bleeding and cramping to go on? I feel so alone in this... my husband has been distant and doesn't talk about it. I told him earlier that I would be glad when the physical part of the mc was over... he didn't even reply.. didn't ask how I was doing or anything! I honestly think it's just how's he dealing with it, by avoiding the topic... but it really sucks for me... bc I need him the most right now.
