Thank you Jax and Spoomie. I just felt at my age and with my history (2 miscarriages with one live birth in between), I simply don't have time to wait and see. I don't smoke or drink, so I felt the cost of the monitor and the sticks were a worthwhile investment.

I'm happy to answer any questions on it - just pm me. I personally found it easy to use, FF allows you to record it's results on there (although I'm not sure if that is just for those with VIP access - again worth the money) and it was worth every penny. If I lose again I will definitely use the CBFM as m/ccan really play havoc with ovulation.
I am very nervous about this pregnancy but to a large extent it is out of my hands now. I'm happy to report that I'm getting my usual all-day nausea (had it until 20 weeks with my DS) and lovely little cramps that I've decided us baby snuggling in. I have to try and retain a positive attitude and keep my nerve. If I don't I'll never have my rainbow baby.
