Am I having labor signs?

First off, I’m 36 weeks. At 33 weeks my cervix was already shortening from contractions. Also, at 34 weeks found out she was head down. I have dropped. These are my symptoms.

1. Diarrhea, going #2 more.

2. Very tired like I have no energy.

3. Feel sick.

4. Lots of watery discharge.

5. Contractions/stomach tightness.

6. Menstrual like cramps in stomach and lower back, has been happening for a couple days now.

7. Loss of appetite.

8. Feel cold.

Any advice would be nice.
