ok so my period started on august 18th, it was long lasted about 11 days I think this was becuase I had the implant removed durung that time. So in theory (if things go straigh back to normal and I have a 28 day cycle) I should be due on my period on the 15th september. So today is cycle day 18, is it possible to be ovulating now ? The reason I think so is because I had slight period pain type cramps briefly earlier and also EWCM but only a small amount. These are signs of ovulation right ?
