I'm 9w today and I have my second dr. appointment on Friday. I had a great first appointment at 6w3d and saw and HEARD the hb. I would really love to buy a fetal doppler (sonoline b), but I'm afraid maybe it's too early and something will happen to the baby and I will be stuck with a doppler I can't return. On the other hand, I feel deep down that everything will be okay, but I'm just paranoid and worried because I had so many problems getting pregnant in the first place. Would you go ahead and buy a doppler? If you have one, when did you buy it?
