I had sex on the 12th and was ovulating the next day, I'm 13 days past ovulation.. I've had 8 positives on line test, just waiting to confirm with my doctor after I miss my period on the 31st. I'm at least 3 weeks and 6 days. I can hardly sleep at night and I'm always feeling nauseated, and at 10 days past ovulation I had slight cramping. And I'm I can't eat as much. Is that normal? Any more symptoms  I should I know about ?
