Pain in ovarie

After I had my child a little over a year ago, I started experiencing cramp like pain in my left ovarie off and on during the day, but when my period comes I don't cramp bad like I do when i have those spurts of pain when I'm not on my period.. I haven't been able to go to the gyno since my six week check up due to not having insurance. But now that I have insurance again I'm going next month. Could this be a cysts?
