I have been having issues with dizziness and passing out. I am almost 14 weeks. My doc checked my blood pressure laying, sitting, and then standing. When I stood up, it bottomed out so low that the machine couldn't pick it up. She said that it is possible that my baby is positioned on an artery, causing the fainting spells I have been having. She told me to call OB right away but didn't explain what that meant for us. Has anyone ever had this happen? Can I sustain a pregnancy with this issue as baby becomes larger? We tried so hard for this little one! I'm scared!
