TWW Pinching Sensation?

Hey there, I'm experiencing a pinching sensation in my lower abdomen for the last day or so. It pinches, then flutters, and then I feel like AF might be approaching (slightly achy/ "full" feeling). Oh! And I feel random "shocks" in my cervix. As in, it makes me yelp uncontrollably when it randomly happens, lol. 
 I have been pregnant (and lost them) before, but did not experience ANY of this... I'm 6 DPO, AF scheduled to arrive in 10 days. Any one out there feel any of these symptoms?
