I was due for my period on 3/20 but didn't feel like it was coming so I tested in the afternoon on a whim and got a faint positive

Waited until today 3/22 to retest and the line is still faint

I don't know when I ovulated so it's making it hard to judge how many dpo. Was hoping for a darker line today but im starting to lose hope. I had a miscarriage 2 years ago and have been trying since, so I'm even more scared. Husband basically refuses to even acknowledge the line because its so faint. Feel alone and scared 😞
