Pain in your..you know?

Jane • Currently pregnant with my first baby. 🌸👶🏼🎀 She's a girl!! Due October 12th 🏩
Ok so may be tmi but I'm a ftm so idk. 
Anyway I'm 38 weeks exact & the last few days I've noticed a kind of bruised feeling in my hoo-hah when I'm laying down & roll over or move around. Anyone else getting this?? Could it be because my babies head is engaged??
