So my period is supposed to come in about 4 days

I can’t help myself I’m ready to test

I’ve been waking up lately around 2 or 3 am with what I suspect is nausea I’m having heartburn , I ate 23 cupcakes today, I’ve been on a sugar kick for the past week, I’ve had noticeable but not at all sever cramps the past week and a few days, light possible spotting a few days ago, somewhat tender breast, I’ve been sleeping a lot more just feeling extremely drained & oddly I just feel different like something is going on with my body it’s a very strange feeling but just when I convinced myself to buy a test in the morning I’ve convinced myself it will be negative ugh I have no idea what to do
