Help me c:

I was pregnant a year ago, which unfortunately ended in miscarriage. So, I know what that "gut feeling" feels like. Anyways, I am 10 dpo and for the last week I have had bad cramps, nausea, major fatigue, occasional high fever, headaches, and I just have that feeling. But, I have taken 4 tests of two different brands, and they were negative. I'm wondering if I did a test too early, or if I'm just hoping for something that isn't there. Thanks ladies.
