Those babies are your priority right now.

I was pregnant with triplets in 2008 and I quite literally almost lost my liver. Carrying more than one baby is dangerous, and 100% prioritize the health of yourself and the babies over everything else right now.

Do you have family who could come help you without making you feel stressed? I didn't have that, my MIL makes things a million times harder when she's "helping", but I can see how having some one come over a few times a week to help with laundry, cooking, etc... Does your church have a MOPS group? 100% GO! These women will become your family.

As far as your husband goes, continue to pray for him. Ask him to pray for you because you are feeling so weak. Be vunerable and tell him how scared you are.
You may want to think about taking FMLA leave early.

He may be stressed about money. He may be feeling guilty about a sin issue. You need to have a sounding board, but it can't be him right now. It can't be anyone with "skin", because you don't want someone hating your husband after you reconcile. So you can come here and post through this time anonymously, AND you can pray like crazy.
