throwing up

Ashley
I am on cd 13. At midnight I started feeling really nauseous. I couldn't sleep and stayed awake all night. My period was cd 1-7 (normally only 4-5 days) and my DH and I have bd on Saturday and Monday. I got my first flashing smiley this morning, but still felt terrible. A few minutes ago I threw up three times. I don't feel like these are possibly pregnancy signs as it would be too early, but maybe I'm wrong. I have never felt this terrible during my ovulation time. My temp yesterday was 95.5 and this morning was 98.1, it was a huge jump but I'm not sure if it counts because I didn't get any sleep. My cm is ewcm but very light. WHAT'S GOING ON ?
