I have to say if you have not m/c it is likely that the 8 week u/s just did not detect a hb. Plainly said, growth happens at an alarming rate during the first trimester and its possible that you just didn't see that heart rate at your 8wk because it wasn't ready yet. You also need to take in account the possibility of error in fetal age if you didn't know your exact ovulation or LMP.

When does a baby have a heart?
A fetus's heart develops early (3-5 weeks after conception). It starts out as a tube and then grows into 4 chambers around 5 weeks. It starts beating around 5 weeks but usually can't be heard until 7-9 weeks. During weeks 20-24 a fetus's heart heart develops more fully. An ultrasound of the heart during this time can rule out some congenital heart defects (CHDs) just by looking at the shapes of the four chambers of the heart. (Some CHDs are not detectable by ultrasound.) Before birth, the fetus's heart pumps blood oxygenated in Mom's lungs received via the placenta. During this time, an extra pathway (PDA) exiting the baby's heart is left open. After birth, this extra pathway closes and the heart pumps blood to the baby's lungs to get oxygen in the bloodstream.

What if a fetus does not have a heartbeat at 11 weeks?
At 11 weeks unless you are probably unable to hear the heart beat of a fetus with a standard stethoscope. You should be able to pick it up on the Ultra Sound Equipment in your Doctor's Office. Your doctor should also have other equipment that can also pick it up. Most people do not have that equipment in their homes. Your fetus should have had a beating heart for nearly six weeks now. When it started beating, only super sensitive amplifiers could pick it up. Not even ultrasound could get it. Now it is coming into the range where ultrasound can find it. You will need to see your doctor to check the ultrasound or if your doctor told you the fetus does not have a heart beat ask what to do. At about 21 weeks you should be able to hear the heart beat with a regular stethoscope.
