well, i got my doppler rental about a half hour ago. it took a good 15-20 minutes to find the baby's heart beat, i kept hearing mine, and checking my pulse, and it matched my pulse so i knew it was mine....
then i just kept looking. gave up and stopped after 7 mins. thinking it was just too early. then i listened to the instruction cd it came with. i had been pressing down, and you just need to hold it gently. (i guess if you push down you will just move the baby over awayf rom the doppler)
so i tried again, and within 4 mins. i found it. just slowly moving it around cm by cm, it was a beautiful sound, i cried, because i think i had convinced myself that it stopped growing.
we counted and it came to 165 bm. so now i have to do a google search and make sure thats normal for 10 1/2 weeks.
hooray!!!!
