Could I be pregnant? And negative pregnancy test

Here are my symptoms:

1.sore breast

2.tiredness

3.Nausea only at night

4.peeing alot more

5.really bad heartburn

6.sore stomach

7.light cramping on my two sides off and on every few days

8.headaches

9.eating alot more

10.gaining weight

11.my upper stomach hurts (like the place underneath my boob's. )

12.my lower back hurts and has been off and on too.

Thats literally what I been experiencing all this past couple weeks. And yesterday I didn't started. And I haven't been spotting or bleeding so. I know when my period should start and what I normally feel.
