I agree with Sheree - stats really mean nothing when you are the individual involved. Personally, I HATE statistics - they just make you feel more anxious when you don't seem to fall into the majority percntage
I was given 10-15% chance of success with each IUI cycle yet was very lucky to fall pg 3 times from 6 cycles. Conversely, on seeing great little HBs on several of my early pg scans, its meant to mean a 95% chance the pg will continue just fine - just look at my ticker to see how totally irrelevant that stat is!!
NO one, even the best FS knows what any one individual's chance of success is going to be!
