Twin movement

Anyone else feel like they only feel one baba on the move? I'm 17+4 with di di babies. I feel a lot of movement for at least a week, 10-15 times a day but all over on one side of my bump, I feel nothing at all over the other side. My last appt was at 15+3 and heard both heartbeats xx
