A bit confused and lost….

So as circled in photo, that was the day I “started” my period… I literally was cramping that whole day even the day before so I knew it was coming REAL SOON, I’m the 6th I decided to take a nap and hours later when I got up GRAVITY hit and so did the blood, so BOOM thought this was me having my period so mind you ANY OTHER TIME this will happen to me and I’ll use a pad/tampon and sometimes my period will start off as heavy but then it will slow day until the next day, my days on the first day vary to either too much or just a little…. Anyways back to my issue on the 6th I put a tampon in and then hours later when back to the bathroom, NO BLOOD. Put another tampon in and it was literally a small little streak of blood so I’m like okay well it’s coming just slowly, anyways after hours and so on tried again and nothing, I didn’t have a pad at the time so I had to use tampons but I was able to get a pad and no blood on it from the one I had yesterday (I was at a funeral, moving, standing and etc every woman knows how this is on they period)…. Well I woke up this morning and NO BLOOD again…. So now I’m confused what I need to do it says on GLOW that my actual period isn’t until the 8th/9th shown in photo but again I had the blood show on the 6th and TMI but the blood that morning when I got up was like a kiddie pool in my underwear… so days have past and I’m at the point where I’m not sure what to do, just keep waiting to see if I’ll bleed or go ahead and take a test. I’m tired of taking test just to get a negative, or because my period late…
