15 weeks but I was only sure they were Mog because I was listening to her HB on the doppler at the time and heard the kick at the same time I felt it. I've noticed this one moving about a bit when I check the HB, so I assume it's going to happen the same way. I had a huge anterior placenta, and it was a long time before I felt any serious movement and it was always difficult to let other people feel her.
