Is low lying placenta the same as placenta previa? At 28 weeks what are the risks/how dangerous is it? How will it affect rest of pregnancy and birth?

Is low lying placenta the same as placenta previa? At 28 weeks what are the risks/how dangerous is it? How will it affect rest of pregnancy and birth?

Not the same...: A low lying placenta is when it is close to the cervix, but not covering it like a previa does. The risk of either is bleeding, esp. Once in labor. But a low lying placenta is much more likely to move up the side of your uterus & out of the way prior to this. Your dr. Will follow this with serial ultrasounds until then. Probably smart to avoid intercourse & to report any bleeding until clear. ...Read more

Could a woman be pregnant and not know it at 28 weeks and have complete placenta previa?

Unusual: It is hard to believe but it still happens, occasionally, patients come to labor and delivery without any prenatal care or any knowledge of pregnancy and deliver a term fetus. I guess if the person does not know she is pregnant, but realizes this only at 28 weeks after an ultrasound, this can show placenta previa, though commonly patients with placenta previa have some variable amount of bleeding. ...Read more

Maybe: Placenta previa's tend to migrate up into the large(fundus) part of the uterus when it is marginally attached near the cervical opening and the pregnancy goes to term. A ultrasound can confirm its' location. If you have any vaginal bleeding whatsoever, go directly to the hospital if it is bright red and call your OB immediately. ...Read more

Ultrasound: Ultrasound is the main way to follow a previa. If your previa resolves with time, your labor should be the same as anyone else's. If it doesn't, tests for anemia, clotting factors, and blood availabilty are tests that are performed to be prepared for any emergency at delivery. Most patients are at bed rest in their 2nd trimester and pelvic rest until delivery. ...Read more

What is placenta previa marginalis grade 2?

Placenta previa: Normally, the position of the placenta is near the top of the womb. In some cases however, the placenta stays in the lower portion (part) of the womb, and either partially or completely covers the cervix (neck of the womb). The described grading is when the placenta reaches the cervix, but doesn't cover it. ...Read more

Why is there bleeding with placenta previa?

Why is there bleeding with  placenta previa?

Leaky vessels: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US. ...Read more
