I m 17+3 i started having these sinking feeling in my uterus... It comes when i m laying down... It only comes for few seconds but thn it mkes me breathless... I m so worried... Thy hve started to become more frequent... I cnt speak to midwife as center is closed... I hve to call on monday... It almost feels like something moves up n thn somethings moves down... I dont know if its wind causing it.. Sometimes its worst when i need to go for pee...n sometimes it just happens when change sides... Today i hve been feeling thm alot...does ny one else have tht???
