Oh I'm sorry to hear that sweetie.
I hope that you can get the kidney stone taken care of quickly so you can start trying again. I was kinda in the same boat. I went to the doctor to see why I'm not getting pregnant and they found that I had mild displatia and I had to get that treated before we could try again. Maybe that was God's way of letting you know there was something else going on with you aside from not getting pregnant. That's the way I look at it. I am done with my treatment, and now I just have to wait 3 months and get a clean pap and then it's on...
What kind of doctor did you go to to get an ultrasound, and did you have any thing else going on that would have led you to get one done?
I hope you had a good vacation!!! Where did you go?
