I'm almost two weeks late and I never am!! I'm also lightheaded, having headaches, cramps, peeing more etc. I have take tests that say negative. I took one today that had a very very faint line. I just had a blood test that said negative. I am having another blood test put in and I'll go back in a few days or maybe a week and do it over. Idk what to think or do?! Any advice?
