Can I consider this a positive?

Hi ladies, im 15dpo, all of my tests before today have been negative. I just got this today - not my first urine of the day either. I see a line, but this has happened to me before where i get a faint positive and a couple days later i get my period (chemical pregnancy) I don’t want to get too excited yet and not sure If I should tell my husband yet or wait for it to become darker over the next

few days.. I don’t want to crush him if its just going to be another chemical one. What do you think? Is it strong enough to tell him?
