Baby kicking my ?

OMG!!! Okay I thought it was just me. I know my baby is breeched right now (had an ultrasound last week) and so thats definately where her feet are! Okay...so I don't leak pee...uhh...I don't think (wear pantyliners to be safe) BUT...(you'll think this is weird) its sooo hard sometimes I feel it from my to the lowest part of my back. I know that sounds crazy but I swear I feel it almost on my bone. I have a baby ninja I swear!!!
