No period, neg test, could still be pregnant?

Ag
Alright, so it's 12-14 dpo depending if i actually O'd the day I got a +OPK
​No period. I had tan CM from 10-12dpo in the mornings, but no increase in quantity or color throughout the days. Now it's just creamy white. 
​Today I'm having some sharper cramping occasionally... Nothing like premenstrual. 
​Other possible symptoms of preg include cold symptoms around 7dpo, some gum irritation, and moodiness. 
​Should I still test in a few days? I just don't know. 
​Thank you for any feedback or personal experience!
