I'm 9.5 weeks pregnant today. Late last week, I started to feel the baby move. This is definitely not gas. This is my 4th pregnancy, so I get the difference. I'm also showing like when I was 5 months pregnant with my other kids (). I realize that you show earlier the more you have, but this is something. My MIL immediately asked if this was twins, which freaked me out to say the least. I hadn't even told her I was pregnant - so much for sucking it in.

A good friend of mine suggested that maybe I was just further along than I thought (unlikely given the clockwork like periods) and loaned me her fetal doppler to see if I could hear a heart beat. Her reasoning was that if I could then I was probably further along. So . . . I used it. Now I'm more stressed - lol. On the right, I heard 165 bpm. On the left, I heard 135 bpm. These were within seconds of one another. I can also hear my heart rate of 55 bpm, which is my norm. I've repeated this 4 times now, and I'm consistently hearing myself at 55-60 bpm and two other heart rates that are 20-30 bpm apart (but in the 120-170 bpm range).

My question to women who have used fetal dopplers before is this: is one of the faster heart rates the cord/placenta? From what I've read, the "placental rate" would be about mine or a little faster, and the "cord rate" should be within 10 bpm or so from the fetus.

I moved up my 1st OB appt to this Friday instead of 2 weeks from now. I can only imagine his reaction when I confess to using this thing - lol.

I'm sorry but I kind of agree with your friend. Are you absolutely sure? 135 is on the slow side for 9 weeks and the literature I'm reading says the 'norm' is 160 to 190. Actually the PEAK heart rate is slightly after 9 weeks before it starts to slow down again.

Going on mainly the heartrate with a few of your other details I'd say you're probably a few weeks to a month further along than you think you are.

i am 9w2d with twins and yesterday my heart rates were confirmed at 150's for one and 160's for the other. it was the first time they were measured, though we have seen them since 6w4d

there is always a chance that you are one cycle ahead of what you thought and the last period was not real, it happens around here more than i would have ever guessed.

only way to know for sure us get an ultrasound, i look forward to hearing what you find out on Friday

either way, come on over to the January Due Date CLub and join on up! we are a great group!!!

At 14 weeks we heard two heartbeats. There was about a 20 bpm difference between the two of them. There is just one baby in there. I have had two ultrasounds to confirm it.

Hope you can get some answers very soon.

I had a few times where it seemed like we heard two different heartbeats (which ranged pretty greatly) but theres just one little girl in there.

Yes, it could be twins, but it could also not be the only way to know is to get an ultrasound or wait until baby comes along.
