I haven't come across anyone who has gotten pregnant and had the typical cf mucus, but that doesn't mean that hasn't happened-I just can't remember anyone saying that in particular.
Holly catheryn's website might have some info on that.
I use the First response brand(purple box). I used to use clear blue easy ovulation tests, but I like the first response better. For me, they show more of my lh than the blue easy. I don't have one of those expensive machines. I'll keep using these as long as they work ok.
Yes I have a longer cycle, and therefore a longer luteal phase. I think its from coming off the bc-my body regulates itself now and I just don't have that typical "28" day cycles. The doctor isn't concerned with it though. So that's a relief.
