Positive test when to tell my husband?

So yesterday I took a pregnancy test and had a faint positive, today I tested again and it’s darker. Nov we had a miscarriage and it really crushed us, miscarried at 5 weeks. With my miscarriage my line never got darker.

This month is our year mark of trying. (I do have a autoimmune disease)

So yesterday I got my blood tested and go back on Monday to get my HCG levels tested again to see if rising. I started progesterone as well.

When should I tell my husband? It’s already so hard not telling him, but I rather be crushed then us both. Sunday we’re suppose to take our son dirt bike riding, and it’s gonna be obvious that I don’t wanna ride.
