Me and my husband have been TTC for a few months now. I have been tracking my periods and ovulation through Glow & digital ovulation tests. We had sex 4 of my fertile days. I am not due to start my period until Nov 3rd. However I have had some symptoms... I am nauseated when I first get up, back is aching, and today at work I randomly vommited. No warnings before or after getting sick and I feel fine now. Is it entirely too early to take a test? Help!
