Weak heartbeat at 6 weeks cause for concern?

stephbm26

Hi, I am pregnant for the first time after 2 years of treatment for PCOS. I had my second ultrasound yesterday - I thought according to LMP I was 7 weeks but the length of the embryo (5.7mm) apparently puts me at 6  weeks. The Dr doing the ultrasound said the heartbeat was 'feeble' and advised a follow up scan for 2 weeks time. The growth of the sac, embryo etc had been good and all other areas including placenta etc are normal as per the scan.

Is it just that its too early to have a strong heartbeat or do I have cause to worry that something is going to go wrong? I am trying not to worry too much but if anyone has been in a similar situation or can help put my mind at rest that would be great...

I wouldn't worry yet. Part of PCOS is usually having wonky cycles and ovulating late, so it makes sense for your dates to be off.

Did the doctor say what the heart rate was? The heart doesn't start beating until late 5 weeks to mid 6 weeks, and it starts off slow. It's normal for it to start off in the 80's and have it pick up in a week or two.

I don't have any experience with any of that, but just wanted to say best of luck and sending you t&p!

Did the doctor tell you what the heartbeat was?

At my 6 week appt, the heartbeat was 110 at the low end of what my dr said was "normal" so we scheduled another u/s at 8 weeks and all was well-the baby had a stronger heartbeat and was measuring on track. I was so worried for those 2 weeks but as long as I wasn't bleeding or cramping I told myself all would be well. I hope all goes well for you!

Weird. I had one at 5w6d and it was 110. They said that was really good for that time.

their little hearts don't even start beating until 21 days post ovulation or close to that date. I mean it couldn't be too fast.

I'm right at 6 weeks and my Dr. mentioned that the heart beat was a little slow, but its normal because its a brand new heart beat.  I have my next appointment in 3 weeks to do a follow up and get the full pregnancy plan.

My first OB told me we had a weak heartbeat, when it was really on the low end of average. That was at 6 weeks and I am now 32 weeks. Good luck!
