Do I take a pregnancy test?

I still haven’t started my period....Haha but the last time that I was quite late for my period I used up a couple pregnancy tests (both got negatives.) Then I literally started my period an hour after I took those tests. 🤦🏼‍♀️ I’ve never had regular periods so I’m not sure what I should do. Should I wait a few more days? I’ve also been SO SICK. Like this past week I even have been dreaming about how nauseous I am. But I know most people don’t even feel sick this early. So I’m worried it’s just me being sick with something else. And just being paranoid. Haha I don’t know. I just hate wasting pregnancy tests. And I’m afraid I’ll start AF as soon as I take a test.
