Feeling of something in my belly now! 13 weeks today 😍

Does anyone else notice that when they're sitting or lying and go to stand up that there is like a lurch kind of feeling like a mass has moved! So wierd 😂. Its like when you're driving and go over a hill and feel your stomach lurch upwards. So wierd lol. Started in the last few days and now i definitly feel pregnant 😍
