Weird symptoms- could it be?


I ovulated on the 3rd. My cycle usually starts around the 14th (give or take 3 days). I’ve been exhausted the last two weeks and been having extreme sweating spells. I come home from work and nap for 2 hours and still sleep a full night. My nose has been a little runny and a light headache. I’ve taken a test the last 3 days and they all look negative...

Am I just testing too soon or do I just need to face the harsh reality?
