10 DPO! STRANGE SYMPTOMS..

I've been experiencing mild twinges in my stomach, mild cramps but not like period cramps, nausea & headaches for the past 3 days. My CM has also slightly increased. I havent taken a test yet, im scared of a BFN :( glow has told me to wait until tomorrow but im waiting to see is AF shows up I have never had these symptoms after ovulation or before AF. 
​Can someone give me some honest tips? Could these just be false alarms? Could it all be just in my head? Idk
