Hi Nat
So pleased for your re no consultants.. What a relief. Lets hope you get the homebirht you want...
Did you have HB for DS1?
Etch-a-sketch thing sounds very cool. Like the timing too, right before DS 1 goes back
Clairey... - no harm in going for it from CD 7 as sperm can live inside for a few days but CD7 might be a bit early for optimum time. Did you get any EWCM? Once you know roughly when you ovulate it will be easier.
If your cycle in 27/28 days long you may well ovulate at day 12 to 14, so I'd GOF for another couple of days yet!
Depending on length of the luteal phase (bit from ovulation to period starting) you can work out whether you ovulate right in centre of cycle, early or late... I think most women have a set length to their luteal phase. There is assumption by books etc that all cylcles are 28days and ovulation takes place at day 14.
But if you have e.g. short luteal phase like maybe 11 days you might have 28 day cycle but ovulate as late CD 17
Sorry have written an essay.... I always had crap cycles from year dot and so monitored all this stuff closely for years.. hope that helps sorry if there is any hint of teaching grandmother to suck eggs about it !
