Pregnant and haven't told my husband.

We had a loss a while back and he didn't take it so well. Be even stopped trying for months. We do not trying not preventing method. No tracking just make love, well I'm pregnant. I'm excited but I can't bring myself to tell him yet. I know this is wrong. However he hasn't asked or anything. I am going to tell him in about a week if my spotting and mild back cramps subside. Otherwise I don't want to get his hopes up and then miscarry again. I'm not prone to miscarriages as we have three children but still I'm nervous.
