This position allows the cervix, or the entrance to the womb at the bottom of the uterus, a clear path for delivery. When the placenta covers the cervical os during the last months of pregnancy, the condition is known as placenta previa.
Most pregnant people with placenta previa will require pelvic rest. This typically includes abstaining from having sexual intercourse, limiting any procedures like an obstetrical check for dilation, and possibly restricting any exercises that may strain the pelvic floor.
The main symptom of placenta previa is sudden light to heavy bleeding from the vagina. Any bleeding can be representative of problems with the placenta and needs investigation by a physician. Specific symptoms may include:. Pregnant people who are smokers, who are older than 35, or who are of Asian descent are also at higher risk of developing placenta previa. Usually, the first signs of placenta previa will show up during the routine week ultrasound.
These initial signs are not necessarily a cause for worry, since the placenta is often lower in the uterus during the early part of a pregnancy.
The placenta usually corrects itself. According to the Royal College of Obstetricians and Gynaecologists , only 10 percent of people with low-lying placenta at 20 weeks will have a low-lying placenta at their next ultrasound.
If you experience any bleeding in the second half of your pregnancy, doctors will monitor the position of the placenta using one of these preferred methods:. A low-lying placenta can be associated with painless, bright red bleeding from the vagina during the last 3 months of pregnancy. If this happens to you, contact your midwife or GP immediately.
After your baby's born, part of the placenta or membranes can remain in the womb. This is known as retained placenta. If untreated, a retained placenta can cause life-threatening bleeding. Breastfeeding your baby as soon as possible after the birth can help your womb contract and push the placenta out.
Your midwife may also ask you to change your position for example, by moving to a sitting or squatting position. In some cases, you may be given an injection of a medicine to help your womb contract. Placental abruption is a serious condition in which the placenta starts to come away from the inside of the womb wall.
