Possible symptoms?

Laura • Straight edge, vegetarian, feminist, lover of animals.
I think I am having some symptoms maybe? 
I'm 10dpo, 5 days away from AF
I have been experiencing:
Cramping kinda like AF
Constantly feel "wet" 
Slight nausea 
Feel real dizzy only when I first stand up though
Very painful breasts, like woah. 
Should I test? Idk I'm super nervous !!
