or you can go to pregnantin3months.com and get the ov-watch for $189 and enter in the 3FREE code and if you are not pregnant in 3 months they will send you three sensors for free. That is what I did and I am on my first month using it. Got my fertile days already so now i am in the 2ww.
hopefully soon. I asked and they are working on it.they don't ship to the UK yet though
