BFP and keeping it a secret?

Samantha

So I’m only 6dpo and trying for baby #2. I really feel like I am pregnant and am dying to take a test after my son goes to bed. The only thing is I do not want to tell my husband tonight if it is positive. He has a man cold and is cranky and will ruin the whole thing if I tell him tonight. I’m terrible at keeping secrets but I really want to know... ugh. What would you do??
