So the other day I was cramping and it felt like I was about to start my period, well I didn’t and the cramping stopped it only lasted that one day off and on, well now I’m 2 days late and still was just patiently waiting thinking it would start. Positive opk cd14 tho so maybe it’s not even technically late? It’s cd29 anyone  experience this and know what could’ve caused the cramps if no period?
