Sex after miscarriage

I don't really know what I'm looking for here, advice, maybe? I don't know. About a month ago I miscarried. This was our first pregnancy and we had been trying for a while months. My husband says that whenever I feel mentally and physically ready we can start trying again. But, I don't even feel like having sex, with or without condoms. The thought of it makes me both sad and terrified. Sad because it's a reminder of what we lost and terrified because if we get pregnant again I'm terrified of losing another, but I'm also terrified of not losing it. I know I just need to get over it, but it's hard and I have so many thoughts. I'm also pretty sure that I have an ovarian cyst (I've had a few over the last couple years) and it's causing some discomfort so I think sex would make it painful right now.
