So i habe been having headaches, backaches, sore boobs, occasional light cramps& i get nauseous EVERY time i eat. AF isnt due until 8 days and i took a pregnancy test this morning but it was negative. What do you guys think. Id like someones opion other than my moms who just blames everything on my nerves bc i have really bad anxiety.
