You can also try an ovulation predictor kit, although having an LH surge does not necessarily mean you ovulated. Most women ovulate 14 days before the start of their next period. Some women have no signs or symptoms at all, but most will have a thicker, stretchier clear discharge just prior to. Other then that, the only way to know for certain is medical testing. Good luck.
You didn't mention how you are tracking your ovulation. Are you using a basal thermometer? Are you inserting your fingers into your vagina to check for the "egg white" and the position of your cervix?
Have you tried the ovulation tests that you can buy at most stores now? Try checking around the 10th day to the 17th day after your period starts. This is when "most" women ovulate...so they say. lol
Good luck
