Girls, can you guys also have this? We had an ultrasound at week 4, everything was said to be good. We're 20 weeks pregnant, it's pushing all over, but a pain has appeared on the right side of my belly, like a tingling sensation, especially if I'm standing up for a while, sometimes it goes down to the back. Maybe someone else has experienced this? Should I worry or maybe the baby is lying sideways? )
