Try your best not to worry hon. As everyone else has said, it's not uncommon at all. I had to have an urgent checkup this week as I fell on my tummy and the midwife told me she was hesitant to use the doppler as she may not be able to find the heartbeat which would only lead to more stress. I'm 19 weeks and my placenta is posterior but the midwife said it was still unlikely she'd find it. She did actually find it without any problems but my little one is sitting right at the front - I can feel where it's positioned most of the time - so I was a bit of an unusual case.

I'm sure your little bubs is just fine honey. Midwifes often say they're hesitant to use dopplers because they can cause unnecessary stress.

Take care of yourself
