I do have a doppler but cannot find anything with it yet. It probably does not help that I have a lot of loose skin and belly fat. If I push the probe down, half of it disappears.
I also think it might not be working correctly as it was not even displaying the BPM for my heart beat. The company I rented it from has already sent me a replacement that should be here in a couple days.
It was also interesting to learn that the company I rent the doppler from claims that the 2mhz probe is the strongest. The medical supply places that actually sell the doppler claim that the 3mhz is better for early pregnancy detection. I'm hoping that it's just too early and I have too much flab in the way.
Everyone's responses have definitely helped to chill me out some. I'm not cramping or spotting so hopefully that means everything is okay. I think I will wait on the u/s. If I win the lottery, I am so buying my own u/s machine.
