thanks for this pinksprinkles, I am in my second month of charting, first month was very dodgy & it doesn't appear that I o'd at all, this month I am finding it easier & am making sure I temp at the same time each morning, also this month I am trying to understand my cm & cervix position, I tried to do it all last month & ended up just stressing myself out way too much so decided to just concentrate on temping correctly.
Feel free to take a look at my chart & let me know if you think I am going wrong somewhere!
I just checked out your charts and your doing a great job of charting. You're really not doing it wrong at all!
Looking at your temps from this cycle and last, it looks like last cycle you probably ovulated around CD 10/11. See how all you temps before then were a lot lower and then it jumped up to a higher range? So I would guess you O'd around there. It will probably do something similar this month, temperature-wise.
I know you didn't get a positive OPK, but it is possible you just missed your LH surge based on when it happened and when you tested. Which OPK's are you using?
I think that this month will be a lot more clear to you since you started temping on CD1 and you are checking your CM and CP.

If you have a slower rise after O, other signs can really help in knowing your O date.
