Need Advise PLEASE

We suffered a miscarriage earlier this year. We’ve been ttc again since August and this morning tested positive.

I’m about 12 dpo and af is due this Sunday. Late this afternoon i started having light brown discharge and I’m so scared this time around.

Of course I want to tell him but I don’t want to get his hopes up for no reason :/. I’d rather be the only one to know and have heartache instead of him having it with me.

Should I tell him anyway?
