First time for everything...

So I just got married two months ago. And I’m 34 so we’ve decided we’re not trying trying to get pregnant but whatever happens happens. I’ve still been tracking ovulating and things like that. So my period was supposed to arrive yesterday (so 2 days late now) I’ve taken a pregnancy test and it was negative. I’m not showing any symptoms of starting my period though. No cramping and the last few weeks prior I’ve felt different but it was too early to tell. I’m going to take another pregnancy test in the morning. However, what happens if it’s still negative... do I just keep taking one everyday? What if it still shows up negative and I never get my period? Totally new to all this and not sure how to process all of it!!
