All of these websites are very good but I'm so happy I went to the one recommended by Lues. I'm always reading about how people get early ultrasounds and found the heartbeat at 5/6 weeks. However I was 7 weeks exactly when I had an ultrasound done and it only showed the gestational sac and yolk sac. Being that I am prone to early losses I assumed that I was in for another miscarriage (the ultrasound tech even made it sound like there was no hope for me) but then I went to that website that goes day by day. Lo and behold on the 7 weeks page and the ultrasound on there looked exactly like mine! So now I have hope! Thank you, thank you, thank you for starting this thread
