Horrible day. 10 weeks.

Yamil
Went for my first sonogram today. First, the nurse called me on phone, "make sure u drink water". When i got there, she claims she can't see the baby bc I drank too much water. So, I had to pee. Now she says, " oh ur bladder is empty, it's so hard to see the baby but I only see something that looks like 7weeks on one side and 8weeks from this other side" what the hell? Then she said, or u want me to do it internal?. Hell No. That's enough, I would rather see my doctor which is tomorrow. At the end, she said I might have miscarriage without knowing. This is a free pregnancy place and I think their machines r really old. Now, she made me so stressed to see my Dr tomorrow. How can u see 8weeks and 7weeks
