Could I be pregnant??

Tiffany
So my period isn't due for another week and a half and I'm about 8 dpo.  Usually when I ovulate I cramp and this lasts a day, two days max.  I've been cramping for the last 8 days.  It's not period cramps because those are more severe and put me in the verge of tears. It will not go away.  I've also been experiencing acid reflux every day and I haven't experienced it like this since I've been pregnant 5 years ago.  I've been having headaches and feeling nauseous to the point where I've ran to the bathroom even out of my sleep because I felt the urge to throw up but then nothing comes out.  I'm not sure if I'm being paranoid and I don't remember having any symptoms so early with my daughter but every experience is different right.  Maybe I'm just being paranoid but I know it's too soon to test.
