Thanks for your reply Dragonbub

I am charting and temping. Had a positive OPK a few days ago and have had EWCM for a week. But temps are doing a sawtooth pattern - basically going from 36.3 to 36.0 and back up and back down... !! Fertility Friend also says that O hasn't been detected I'm on CD18 now and usually O about CD14. Have jut realised my temps are usually climbing steadily by now, seems like something weirs is going on.

The only thing you mentioned that I don't do (and don't really understand) is checking cervix position.
Do you think any doctor might actually organise regular blood tests for this purpose? I am starting to feel like I'm wearing sunglasses at night!

Thanks again...
