Hey ladies. I've been charting my BBT, cm and using OPKs since we started TTC. This is our 4th cycle. The top 3 charts are Jan, Feb and March cycles. As you can see they are a little jagged. I was taking my temp at 5.45am every day and it was always after 7 hours sleep so I decided to change to temp vaginally to see if it would settle my temp. As you can see by the bottom chart it is much more consistent. So, for those of you that have a spikey chart and find it frustrating I'd say switch to vaginally! We used conceive plus this cycle so I am hoping we get our BFP next week!
