Confused about baby's heart best on doppler

[xQuinnx]

I think I managed to find my baby's heart beat at around 9 weeks and a few days and it sounded like mine but was much faster. It sounded the same for about a week and a half but I listened to it tonight and it sounded slightly different...now it sounded like the 'galloping horse' other people have mentioned. Beore it sounded like a 'thud thud thud' really fast now it sounds like it's got 2 beats so a bit more a 'da-duh da-duh' sound really fast.

My question is this...which one is the heart beat? Is what I heard before wrong? Does the heart beat change near 13 weeks? Is it because baby's bigger I can hear it clearer? Or is there another reason?
Thanks in advance

the swooshing noise would be the placenta, the babys heartbeat would sound like yours but faster and you may hear another noise with the heartbeat. I found mine today and im 9 weeks. the farther along you are the more easier it should be to find. Sorry if I did not answer your question correctly.

My babys heartbeat has slowed down a little since i first found it at 9w3d. At first it sounded like a washing machine going real fast. Now it seems to be beating more stronger if you know what i mean? Slower, but stronger. At 8w3d baby hb was 170 and at my 12w6d ultrasound it was 140. Baby could've just been sleeping, but i've noticed a change since i first heard it.

Thank you for the replies it was easier to find well when I realised what it was! And it sounded much clearer it was just strange :-/ I've got my next midwife appointment on 1st April and she said she would listen to baby with a doppler then
