I’m having the weirdest sensations in my stomach,besides having abit of an upset stomach. It’s twingey,tingling,fluttery? 
I’m hoping these are good signs!
 Testing tomorrow at 10dpo :)
Also had a sudden onset of nausea and heartburn earlier today but that's gone now.
And very sore gums for about three days?
