I don't know what to think

Erica
Last night, my husband and I just went through our 3rd MC in the last year, all were at around 4 - 5 weeks.  This one was the hardest on my husband.   Now he isn't sure if he wants to try again.  He's having a hard time dealing with it.  We don't know what's causing them .  I am scheduled to meet with my dr about some testing to see if they can figure this out.   I don't know what to do or say to him.  He thinks that I don't understand  how he's feeling.  I feel lost.
