So I went in for my first u/s on Friday. I was 7wk2d pregnant. Everything looked fine on the u/s, but my Ob said he didn't see/hear the heartbeat yet and that I should come back next week <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/irked.gif" style="border:0px solid;" title="irked">:. Of course, I get home and start looking all over the internet and then the intrusive negative thoughts start happening...by the time my husband got home I'm crying uncontrollably <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/mecry.gif" style="border:0px solid;" title="crying">.<br>
So...I finally have enough courage to ask you mamas - what is the normal range for heartbeats to start? I remember my last pregnancy my Ob didn't even want to see me before two months. My DH also talked with our friend, an MD, who said it's not uncommon for the heat to start beating at 8 or 9 weeks. I'm so <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/confused.gif" style="border:0px solid;" title="Confused">:...any advice??? TIA<br><br>

I've heard of some not being able to find the heartbeat (not that it's not there though!) until sometimes as late as 10-12 weeks, especially with just a doppler. I think that 7 weeks is still a bit early, so try not to worry!

<table border="0" cellpadding="6" cellspacing="0" width="99%"><tr><td class="alt2" style="border:1px inset;">Generally from 6 ½ -7 weeks is the time when a heartbeat can be detected and viability can be assessed. A normal heartbeat at 6-7 weeks would be 90-110 beats per minute. The presence of an embryonic heartbeat is an assuring sign of the health of the pregnancy. Once a heartbeat is detected, the chance of the pregnancy continuing ranges from 70-90% dependent on what type of ultrasound is used. <i><b>If the embryo is less than 5mm CRL, it is possible for it to be healthy without showing a heartbeat, though a follow up scan in 5-7 days should show cardiac activity</b></i>.</td>

Good luck next week! Don't give up hope.

Was it an ultrasound on the abdomen or a vaginal ultrasound? I think you can usually see the heartbeat around 5 1/2 weeks, but sometimes it isn't detected until a little bit later. I hope you get positive news next week!

Oh sweetie try not to worry! If there was something wrong the doc/mw would see something! You are still in my prayers though!

Like the other girls said, try not to worry. You are still pretty early. The doctors here won't even see you until 10 weeks because it can be hard to see the heartbeat before then. Stay strong and positive!

Unless he was using an internal ultrasound you wont hear a heartbeat till 10-12 weeks.<br><br>
I think 6 1/2 weeks is when the heart beat is visible/audible with the internal u/s probe.

I saw/heard my son's at 6wks exactly via internal u/s, but I've since read that's definitely not the norm. But it is possible!

thank you mamas so much for your kind replies. I did have a vag.u/s at 7 wk 2 d. It looks like if the embryo is less than 5mm it's still possible that the hb will start later. I'm preparing myself either way and I'll keep you posted...

Very good point! With my son my lmp was Jan 2, but he wasn't conceived until around Feb. 9th.. what a shocker that u/s was!
