12 Week Wonder

Pr
Everyone else at roughly 12 weeks gets my hopes up because they get profile shots and talk about their baby moving...well I think mine was taking a nap on its side, which my husband claims it gets from me hahaha! Anyways, I was wondering if anyone would like to guess gender? Heartbeat went from 171 @ 9 weeks to 160 at 12 weeks! Also, does anyone know what the other black spot is? Could that be my bladder?!
