Herbie,
I would recommend doing the free online fertility friend course, its really helpful when starting out and even when your not.
When you have charted for a while you will see what your normal LP (luteral phase) length is. It is "usually" 14days for some women, although can vary to being much shorter. This will give you a good indication of whats happening next cycle if there is a need for one.
What time did you get up this morning? I noticed an open circle on your chart. FF dont recommend it ,but you can temperature correct your waking times on there if its just a one off sort of thing. Its only based on averages so wont 100% accurately reflect it. You have to be a VIP member to do it. If your not, im sure if you posted your normal waking time, your waking time today and your temp someone will help you out.
