The ultrasound tech said I have an AP, but I haven't noticed much different this time around than with DS.
Early on though it felt like I had way more inside movements than outside movements. It felt more like baby was moving/kicking toward my back or down toward my lady bits rather than out behind my belly button. Now that baby is a lot bigger I'm definitely getting a lot of outside kicks and movements too.
But I'm pretty sure I'm not the norm for an AP.
