Hi ladies -
Unfortunately, our ovulation calculator only goes to a 44 day cycle. Have you tried our Ovulation tracker? You'll be able to use that no matter how long your cycle is, and you can chart your BBTs, cycle days, predict using OPKs and FAM, etc. After you've entered in a couple of cycles (and you can go back and enter previous cycles), and entered some of the tracking info (BBT, OPK, etc), it will be able to show when you are likely ovulating.
You can add it here -
