Hi guys

This is my 2nd cycle ttc with baby no2, thought I'd try charting this time as well because I only have 1 Fallopian tube and so want to stack the odds in my favour. But am really struggling with it. I can't really do it perfectly as DD1 is occasionally up in the night, so I don't always get the 4 hours sleep before temping.

Anyone who has experience in temping want to hazard a guess as to what's going on and when I ovulated? I tested this morning and got a bfn. Any help/advice would be really appreciated!!
