Help ladies!!!

Hello everyone!!! 
So I was supposed to get my period Tuesday and I didn't. I wake up Wednesday morning and I go to the restroom and I clean myself and I see a blood. So I thought oh she's here. 
So I was wearing my regular mini pad because it wasn't heavy. This happened early Wednesday morning (yesterday). Then throughout the day I didn't bleed again. Then I got home at night time and I was spotting when I clean myself so I thought oh she is seriously here. 
I definitely thought I got my period so to go to sleep I was wearing my regular night pad. I wake up this morning and I see is a brown spot. And when I go and clean myself there is no blood but just a brown spotting. I had little craps and everything. But I don't know what's going on? 
Please help!!!
