Pregnancy Symptoms

I'm on cycle day 15 of 25. Which is about 3-5 dpo. 10 days before af. Usually I'm not a symptom watcher, but this is what I'm experiencing. Tell me what you think. I've had headaches everyday, indigestion, cramping so bad, a backache terribly but not in my back more like hip/butt area, I can smell anything and more, moody, and tmi but loose stool. Also after ovulating I'm usually super dry butt I'm noticing alot of thick white cm. Maybe prego? What symptoms did you guys get?
