If I dont get this bfp this time hes going to be so sad ...

My husband keeps insisting I'm pregnant :/ j haven't told him I've already taken a test and it we negative. According to glow I'm 8dpo but according to a different approach I'm only 4do. I didn't test so I don't even know if I ovulated at all ...just assuming I probably did given the fact I know that I do... I'm waiting until at least March 6th to take another test if AF didn't show first. Just afraid we are going to be let down again we when really thought we were doing it right this month :/ maybe I tested too early but I've seen others get positive at 8dpo so it's hard to have hope at this point ;(
