Driving myself crazy!

So af was due last friday 7/14, the days prior to I was experiencing all kinds of symptoms of pregnancy, sore breasts, taste aversions, fatigue, dizziness, nausea, cramps, etc. my periods are very regular with no cramps or symptoms at all, I started bleeding Monday evening after getting a negative at home test (it's was a dollar store test). I have not stopped bleeding ever since but it is very light while I normally have a pretty heavier period. I'm still experiencing many symptoms & I don't know if it's my period or not, help!
