These are pictures of my 8 week transvaginal ultrasound. I also got a video of the heart beating, and the close up picture is what they got from measuring the heart rate. Looking closely at the video on the right corner (circled)  there is this little black spot that pulses like the heartbeat. Not too sure this is the placenta, does anyone think it could be another baby hiding in there? I wish I could post the video.  as anyone ever had an early ultrasound show 1 baby and then go back for another and find 2?
