15 Weeks Pregnant - I felt my baby move!

During the week I ran a poll on my Instagram stories asking for votes on when I might feel baby move for the first time. For reference, I said that I felt my first moving at 19-20 weeks with anterior placenta, and my second at 17-18 weeks with anterior placenta. This time I have a posterior placenta, and I asked if people thought I was likely to start feeling movements from 14-15 weeks, 15-16, 16-17, or 17+.
