As of today I am 27 days late for af, and I have taken 3 negative tests. They were all different days and the second and third test were taken with my first pee. I took the last test about a week ago. I started to feel nauseous yesterday evening and all of this morning. I have sore and swollen breasts, bloating, extra back pain on top of my other pain, and I just feel all around different. Could I have tested too early? Am I just skipping a period? Am I pregnant?
