Head or bum lol

April • mum to baby girl 💖💗🥰 born 01/05/19 💗☺️💋

Ladies I’m 30 weeks now at my 28 week scan baby girl was frank breech, anyway this past week, I have felt like lump now at top of my belly ? Is it her head or bum has she turned , because at my scan her head was on my left side bum down then her feet on my right which seemed correct as all her kicks were oh my right hand side. How do I know if it’s her head or bum, 😂😂🤷🏽‍♀️
