Maybe it's a sign

Cassie • 🎉🎃🍁🍂 blessed with a beautiful 3 year old boy a 2 year girl and a 9 week girl👨‍👩‍👧‍👦
Been on my birthing ball all day today and only recently after being on it my tummy has become so hard and sore, I'm having pressure in my bum and can hardly walk properly without my little girl poking out the sides of me and my bump hurting....could this be a sign labor is approaching xx
