Well, as much as I respect the ultrasound, HCG appears as soon as an egg implants. HCG levels will double app. every 48 hours in early pregnancy, so a positive will show up in bloodwork before anything can be seen on ultrasound. It is the best way to know for certain at this point. Give your Dr. a call and see if you can't have one. The waiting is the worst and if you are 2 weeks late for your period, I don't think there is anyway the hormone wouldn't show up. Good luck again!!
They werent a hundred percent sure if it was a baby, and said to wait a few weeks cause if it was it wouldnt show up on a test by the looks of it, I saw it, it was just a little dot. My mom was the tech that did the ultrasound so she told me every little thing she saw.
It sounds to me like you need to get bloodwork done. You should also try another home pregnancy test. I am actually a bit surprised they did an ultrasound, said it might be a pregnancy, yet didn't test your HCG levels. Once you have missed a period, blood tests and home pregnancy tests should be accurate. I wish you luck, I hope this is a pregnancy!!
