Little confused

Lillie

So I don't really know much about pregnancy because I've never actually been pregnant but I've been showing a lot of common symptoms. Back pain, diarrhea, nausea..etc. I took a test (rapid detect 1 day before my expected period according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>) and it was negative but I feel like absolute garbage and I have K health and all the symptoms I provided are 60% likely to be pregnancy (I know k is not a doctor but I use it to get an idea of what may be wrong just in case it's serious) so should I wait and take another test (and how long to wait) or could it be something else? Thanks
