Pregnancy signs with negative test

Ka

I have a headache, my boobs are sore, I’m nauseous anytime I eat or smell food, I feel like I’m gonna barf but don’t. This has been going on for a week now My temperature is at 97.0 and I had sex 3 weeks ago and my next period isn’t due till around the 22nd. I took a test 2 days ago and it was negative. I’m going to the doctor later tonight.

I don’t know what else this could be other than pregnancy. Anyone have any suggestions??
