Should I get another test ??

A little back story me and my boyfriend met in high school we dated for a few months then went our separate ways for a while and ended up picking up where we left off. We’ve been together for a little over a year now (we’ve known each other for 5) and we been havent used “safesex” consistantly through the relationship, which I know isn’t the smartest but he says he wouldn’t mind having a baby with me because he plans to marry me. With that being said My periods 24 days late but my periods are irregular so I didn’t think much about it but just to be safe I took 3 test on different days after I was a week late and they were all negative, Im not sure if I should go get another test or if I should just wait to see if my next period comes because it’s suppose to be coming soon according to this app.
