Yeah, some people can't see/hear heartbeats until around 8 weeks....don't stress just yet. You could always have Hcg levels drawn on Mon. and again on Tues. to see if they rise...if you can't stand the waiting game until Fri. (which I would probably do b/c I'm a freak!). You can just call you OB office and they should order it for you.
I didn't see a heart beat with my son at 6 weeks, but then I did at 7 weeks. A few days make a HUGE difference this early in pregnancy. We saw the heart beat with this one at 8.5 weeks. Hang in there, I know the waiting is horrible but keep positive thoughts. My doctor always said if you are not having any cramping or bleeding, stop worrying (easier said then done I know). We tend to focus on the negative - 20% of pregnancies end in miscarraige, but that means 80% DO NOT - so think positive!!!!!
next u/s is on Friday, Feb 29th. The reason I am being so doubtful about this is because of the fact that I had a positive HPT over 3 weeks ago....transvaginal ultrasound surely should have shown heartbeat since the pregnancy has to be at least 6.5+ weeks in order for me to have gotten +HPT, right??
unfortunately the only way to tell will be to wait for your next ultrasound, you should be able to see a heartbeat by then, sometimes calculations are a little bit off and you might be a little behind what you are thinking..good luck!! whens your next ultrasound?
