confused and not sure what to do

So I posted a few days ago with a picture that I was spotting pink blood on tuesday. I thought it might be implantation bleeding (because I have never spotted in between periods) but today is day 4 and I'm still spotting only now it's a tiny bit more red. I've been so very nauseous all 4 days and can barely eat. I also have been feeling dizzy, light cramps, and mood swings. My period isn't suppose to start for another almost 2 weeks so I'm not sure what is going on. Any suggestions? I thought I was maybe preganant at first but I'm beginning to think not. Should I wait it out and see if I get my period?
