Canuck I've not heard of anyone opting for a natural FET, I think my own cycles are way too screwy to contemplate that. All you can do is ask. I think with the drugs they can plan thing more easily going natural you might have to be prepared to stay longer or have your cycle cancelled. I'm not sure why you'd go all that way adding so many variables into the mix. I don't find the drug protocol too hard going. Having said that I don't take the bcp due to factor v.
