I was just wondering what's the earliest you've heard the HB via doppler (at the doctor's office)?
I had always heard that it was usually 10-12 weeks but mostly closer to 12 than 10 but when I went for my appointment I managed to convince my OB to try even though he said it was unlikely he would be able to find it on the doppler (I was 9w1d) but he found the HB almost right away (188 bpm). We later went for an u/s to check on a small SCH I had in my previous u/s and the HB was pretty close to the doppler's measurement. Anyway, I was just curious. I assume it's maybe because of different qualities of equipment. Does anyone have any other thoughts about this?
ETA: Transvaginal u/s can usually detect the HB around 6 weeks but that seems to be fairly standard. I'm asking specifically about the doppler because there appears to be so much variation.
