Late period, BFN?

Did it take anyone a while to be able to get a positive pregnancy test or only got a positive blood test? I’m not trying to get pregnant but we do use the pull out method, and I would be happy if I was pregnant. I’m 9 days late and have taken 2 tests and they were both negative. I took one a few days ago and one yesterday morning. Idk maybe I just ovulated late 🤷🏼‍♀️ haven’t really been feeling anything besides being tired and I felt some slight cramping yesterday and I’ve been nauseous on and off for a couple days, but that happens to me sometimes like even in other months lol
