luvmi2kids ~ I can't remember what your original question was now. Anyway, I don't see O on your chart yet. As long as your environment is the same, it shouldn't matter if it's cold all the time or hot all the time. The temp in your room would only matter if it changed dramatically overnight and that's just a possibility. That you are taking your temp several times each morning and picking the one you like best to record may be why you can't see O on your chart (if you did O already). You need to pick one time and use the temp at that time consistently whether you like it or not.
Twinkle ~ Hope this is it for you. You may not have to worry about that earlier high temp since you've got 6 temps after it. I guess it depends on whether or not FF ignores the open circle temp right after the high one.
Canid ~ I knew you couldn't stay a way.
I know your dh is all for another baby. He seems to be the oddball. Maybe you can get him to talk to the rest of our guys.
texas ~ You need to stop temping now. You'll drive yourself nuts wondering about each fluctuation. That's what I did, anyway, after getting pg with ds2. My temps kept going up, down, up, down and I was giving myself a nervous breakdown so I stopped temping.
Your chart is a little hard to interpret. Based on your temps I'd put your CL at 97.7 and guess you didn't actually O until possibly cd19. That intrepretation depends a bit on why your cd 16 and 18 temps are open circles. Based on CF, O may have been cd15 with a slow temp rise. Sometimes it can take up to 3 days after O for your temps to reflect it. Also, it is possible for CF to dry up a day or two before O. Charting is really only accurate to within 3 days of O. When cta especially, it's important to go with the latest possible O to make sure you are absolutely safe for unprotected sex. Whenever in doubt, always assume you are still fertile and act appropriately. (You probably already know all that since you've charted in the past.)
