Dealing with resting

So I am 12 weeks with my first pregnancy with twins and I have had some spotting and yesterday I thought I was having a miscarriage because there was a lot of blood but it stopped and I haven’t had any pain at all. So I’m taking it easy until I can talk to my on and see the babies. My husband is now having to clean and do stuff around the house while I rest. He insist it’s okay that it sucks but it’s okay. I feel horrible that he works and then now has to handle the house as well. How do I cope with this? I’m scared that if I have to be on bed rest it could damage my marriage.
