Pregnancy Problems


I'm 19 days late for my period and this isn't a normal thing for me. I've taken two at-home pregnancy tests a week since my first missed day and every single one has said "Not Pregnant." I'd chock it up to being stressed or something funky, but I'm also getting morning sickness, headaches, tender breasts/nipples, acne and emotional spells. (note, those things aren't normal for me). should I bite the bullet and call my doctor?
