I think that's a sensible choice. With two, you should be OK most the time, as even if your estrogen rises, the additional gel shouldnt put you too high. Ironically, if you go up at all, you'd probably be better on 2-3 daily, like that document says, as this will prevent you ovulating at all. (Obviously I am not saying do this - just speaking hypothetically, assuming I have understood the NAPS literature correctly!). With 3, I guess you will still ovulate so your highs will be very high!
After I'd paid, I had an email a day later to which I had to reply, if that makes sense? Dr Currie replied about 4 days later.
Will be interesting to see how you get on x
