I I'm actually late from my period tomorrow will be 4 days late. I have been nauseated and throwing up in the mornings bright yellow with that's weird since I don't have a gallbladder removed, very fatigue exhausted, been sleeping more, my pants don't feet me any more, mood swings are all over the place , very emotional, peeing more often, and eating a lot but I'm controlling myself on the eating section. The brand is (digital clear blue) I took two pregnancy tests and it negative. Am I testing to early? Or when should I test again?? Or what brand should I use when testing again???
