Sometimes, implantation happens close to or on the cervix (which is the mouth of the uterus). Clinically, this is referred to as a low lying placenta or placenta praevia. Women who have this condition will experience episodes of vaginal bleeding which can be very scary. The bleeding is usually painless and may occur at the end of the second trimester or beginning of the third trimester. It may be heavy or light.
Low-lying placenta may be picked up during a routine 20-week ultrasound scan appointment. Your doctor will want to limit your exercises and ask you to rest as much as possible. Having a low-lying placenta means it is more likely a caesarean section delivery will be recommended.
