Karen & Fiona, Thanks for the input. I never even thought about buying a doppler with my last three children, but as you can imagine I am extremely anxious about being pregnant with two (and I'm no spring chicken - I think the older I am, and the more children I have, the more I worry). Anyway, I looked on e-bay and it is just as cheap to buy one on there as it is to hire one... and if it works out to be of no use to me I can always sell it on through e-bay. Yet again, thanks for your input, and I'm glad to see all is well with you both. Good luck x
