So my very regular period, is 4 days late. I've had intense nausea for a week and a half, mild abdominal cramping, and when I lay on my right side my uterus feels tight and pinched. Pregnancy tests have been negative. I want to believe I'm pregnant but I'm so affraid of being dissapointed. With my son I got a positive test the day of my missed period. Anyone have experience with this?
