Im exavtly 23 weeks today, second child. I bent over to get something out of the passenger side of my car and it felt like simething kind of popped or jolted on the left side of my tummy. I'm worried that maybe my waters have gone or ive done something else. I've had no fluid coming out of me and the baby is still moving lots. Maybe it's nothing but it is worrying me still. Anyone else experienced anything similar before??
