Unclear OPK - Cycle Day 14 - Experiencing Period Cramps

Ashley
Has anyone ever had this happen to them... I am on day 14 of my Cycle, suppose to be in peek OV time (Ovia says a score of 9), OVP last 2 days haven't said anything and I'm experiencing what feels like period cramps... My last AF was super light and lasted a day and a half.  Has anyone ever experienced this while OV? Thanks in advance!
