Pregnancy symptoms?

Hi! I am awaiting to take a pregnancy test sine I've been feeling different lately. Do you think these are pregnancy related symptoms?

Currently.. CD 17

(My cycles are around 24-25 days), I ovulated either on 12/25 or 12/26

AF due 1/7

Symptoms I've had so far.. Sharp pains on left side along with cramping, headaches, backache, nausea (yesterday morning only), and tonight I saw two spots of very light pink blood and stretchy/clear cm.

Thanks :)
