13 weeks with my first, 11 with my second. I had 3 altogether from my first by my doctor, so far this time I've only had one, and I'll be 27 weeks Tuesday.
I had only one at 21 weeks for the gender so its been forever scents I seen my sweet little baby boys face.. but my doctor likes to keep the bills down so he only schedules one for you if your healthy and nothings wrong if you want more you can.. but I didn't want to fork over 500 dollars for a second one :)
First time they checked I was like 6 weeks, I believe. Then I didn't get an actually ultrasound and pictures til I was around 11-13weeks I think. I'm 23 weeks now and only got pictures twice of the baby! But I got to see him like 5 times
