Pregnant?

Symptoms:

1. Nauseas

2. Headache

3. Diarrhea

4. Hot than cold

5. Restless/ can't sleep

6. Can't keep any food in my body and have no appetite!

This is the 5th day feeling like this, these symptoms confuse me! I took a pg test 4 days ago and said negative, now my period is due in 3 days and I'm scared to test again despite seeing ANOTHER negative test! What are y'alls thoughts?
