Heart Rate Question (please take a look)

utilaprincess01 · May 2011

Hey Ladies! Hope you're all having a great day.

When I had my first ultrasound last Thursday, the tech told me that I was measuring at exactly six weeks (which is perfect according to when I O'd). I was so overwhelmed by hearing and seeing my LO's heart beat that I didn't remember to ask what the rate was. I noticed last night that my US pic shows me as being 7w0d along. I figured that the tech either made a mistake or was going by my LMP (the nurse practitioner that I had my first appt with didn't seem to believe that I O'd a week later than the "28 day norm").

Well, I just got a call from my doc's nurse. She said that the doc was looking at my chart and US and didn't like the heart rate. She said that it should be a little higher than it was and that they wanted to schedule another US for tomorrow. Of course, my mind went blank at that moment, so I didn't ask the what the rate was.

After collecting myself, I called back and asked about the heart rate. She said she didn't have my file in front of her anymore but that it was in the 90's (94-98) and it should be over the 100 mark. I also told her about the discrepancy in the weeks, she said that if the US was off by an entire week, that could explain the rate being low but that they still need me to come in tomorrow.

So, my question to all of you mama's that have already had ultrasounds is How far along were you when you had your ultrasound and what was your baby's heart rate?

Thanks so much in advance for any responses!

I went today and she measured me at 5w6d and the heart rate was 120

SmittyPants · May 2011

I was 7w1d and the heart rate was 145.

Much easier said than done, but try not to panic. If the tech said you were a week behind and the heart rate reflects that, which from what you describe it does, then everything is probably totally fine.

Keep us posted.

Thanks for the replies, girls. I just want to have some numbers to wrap my brain around.

Smitty, thank you. I'm really not panicking. I know for sure that I wasn't at 7wks a week ago and I'm believing for a healthy pregnancy and a perfect little one

I was about 6w5d and it was 124.

Oatoa · May 2011

I was 6w4d and we heard 120 bpm. Good luck tomorrow!

Thanks so much for all the responses!!!

At my second u/s I was 5w,6d and the heartrate was 101 BPM. At my third u/s today I was 7w,4d and the heartrate was 151 BPM.

ginger514 · May 2011

I had mine at 6 weeks 2 days, and the heartbeat was 138bpm. FWIW, the tech said anything over 90 was good. I was a week off from my LMP due to 34 day cycles, so hopefully the tech went by your LMP and you really are 6 weeks. Good luck!!!

We just had a u/s at 7w6d and HB was 153. Good luck. I hope they just messed up although if that's the case, shame on them for getting you so stressed out.

CalMum_Momma · May 2011

DS was angainst the OWT about heartrates. His was around 175 in the beginning and droped some later in the pregnancy. Don't want to worry you more, but 90s sounds exceptionally low for a baby in utero, but I am no doctor.

ETA: Sorry, I just checked the old u/s pic and it was 170, and I was 8w4d at the time.

KevinJenn · May 2011

I've been told its completely normal. Especially if you are 6 weeks along. I went last Friday - I was 5w6d, baby was measuring 6w1d and the hb was 96. The babys heart just started pumping so it may take a few days to get up to the "perfect" range. I am going back on Friday to check to make sure its gone up. Good luck to you!

sterpstra10 · May 2011

6w3d and was 126bpm. My RE said he was hoping for something around 120. But it seems like there are varying opinions - oh, and the baby was measuring a day ahead.

jenalena · May 2011

Yep .. nothing to worry about. I measured in at 5w6d with a heartbeat at 97... Now, you'll get to see your baby again!

Rileyrenee · May 2011

I went at 6w 3d and the HR was 131bpm.

littlemonster417 · May 2011

at 5w5d our little monsters was 117. best of luck to you!

mama_rach · May 2011

At my 5w5d ultrasound our peanut's rate was 100.

I found this which you might find helpful: At about 5 weeks gestation, your baby's heart begins to beat. At this point, a normal fetal heart rate is about the same heart rate as the mother's: about 80-85 beats per minute (BPM). From this point, it will increase its rate about 3 beats per minute per day during that first month. However, by the 9th week your baby's heart beat will be in the range of 155 to 195 beats per minute. Most expectant parents say that the fetal heart rate sounds like the galloping of a horse.

kclaybrooks · May 2011

I was 7weeks and 4 days and the heart rate was 163. Good luck, I'm sending happy thoughts your way

EricaK28 · May 2011
