Any advice on how to tell partner we miscarried?

ma

I miscarried today at 4 wks and 3 days. So not far along or anything. I’m ok and have accepted it but my husband on the other hand is very sensitive. He doesn’t know I got a positive hpt the other day so he doesn’t know I was pregnant. He does know that I started bleeding last night. This morning I passed an intact “clot”. Confirmed with my dr that I did in fact miscarry.

My husband just started a new job this week. We don’t keep stuff from each other - we are very open and honest.

I’m considering not telling him only because I don’t want to burden him with something he can’t change. Idk. Any advice or thoughts on whether or not to tell him or how to tell him?
