If you were on it from the 16th to the 26th, you were on it for more than 6 days so while you were taking it you were protected, but once you stop, it will no longer prevent ovulation. Actually figuring out when you are ovulating right now will be difficult by using a calendar because having been on the pill for a few days will mess with your cycle. You won't be able to really tell for a few cycles what your regular cycle will be now. The only thing I can think of that may help you figure out when you are ovulating now would be to do basal body temperatures and monitor cervical mucus and figure it out that way. That should be accurate.
