Really needing some advice!

Ok so AF was due yesterday and I’ve been testing every day since Wednesday, so 4 consecutive days and gotten all BFN on the First Response and Dollar Tree brand HPT. If I am pregnant, I’d be 4wks3days today according to my LMP. Not sure when I actually ovulated though because I wasn’t tracking it or anything. But husband and I were pretty active the week of and week after I was supposedly fertile, according to my period tracking apps. I know 4 weeks is pretty early, just thought I’d be getting at least a faint positive by now..

I just want to know if this has happened to other people and they DID end up being pregnant or if I’m out for this month?
