strange feeling in tummy at 15w+5d

B

today I got a weird feeling very low (like where doc said my placenta is which happened to be just above her head at my 3D appt last week). it took my breath away at first but then it was very dull. Idk if this is me feeling baby moving but I pictured her little elbow or foot stretching out or poking me. could this be it? what did it feel like for you?
