AF symptoms

Sara
Feeling discouraged. ?Have a lot of AF like cramping and lower back pain. I'm 10 dpo and my only new symptom is fatigue, feel like I could nap all day and little breast tenderness. 
​I know your not out till AF shows but my cramping feels just like it usually does before period. Ugh!!!
​Was hopeful bc my bbt dropped one day then went up the next which I thought might indicate implementation drop. But perhaps not.  
​Sorry needed to vent.
