I 100% feel pregnant, I just know but all my tests come back negative. I'm now 8 days late. Mild cramping in lower back here and there. When it's my period it's so intense I curl up in a ball or have to squat down. I'm having symptoms that are not normal for me. I'm a emotional wreck. I'm just so frustrated every time I look down and see one line. I'm ready to stop trying.
