Question: Hey Thank you so much for taking your time to answer my question. I had a question: today I had my 20 week sono and I had to lay on my back for 30 minutes. I talked to the doc during the sono and felt pretty fine, except a bit of trouble breathing. But when the scan was over and I sat up, I felt extremely nauseous and extremely dizzy to the point I thought that I would faint. Now, I am worried that I harmed the baby by compressing the the blood flow due to the weight of my uterus the whole time during the 30-min long sono. But if that had been the case, would I not have felt nauseous and dizzy and unable to speak during the scan instead of later once the scan was done?I felt ok during the whole scan. It was not too comfortable but I did not feel nauseous and dizzy. And do you think I harmed my baby since the scan took 30 minutes? Once the sono was done, it was an ugly feeling when I sat up and tried to stand up. I would so much appreciate your advice. And I also have usually a low blood pressure around 90/62. I always lay on my left side in bed. Many many thanks, XXXX

Dear Dr. XXXXXXX XXXXXXX First of all, thank you so much for your prompt response and putting my worries to ease. I am truly thankful. Abut the heart rate changes, I cannot tell as she only looked at the heart beat around 10 into the sono and only checked it briefly. It seemed regular and strong. As the soon took almost 30 minutes, I wonder if it did change but she never checked it again. About changes in fetal movements, I don't really know. The lady did not say much during the soon except answered shortly some of my questions. But again, thank you so much for your time and help. I very much appreciate it. Best regards, XXXX
