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?

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

I;m 28 weeks pregnant with a placenta previa. I bled once and was sent home. Can I make it to term?

I;m 28 weeks pregnant with a placenta previa. I bled once and was sent home. Can I make it to term?

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

Can you tell me about marginal/partial placenta previa and cn it resolve before your due date?

Can you tell me about marginal/partial placenta previa and cn it resolve before your due date?

Yes: Marginal/partial placenta previa is when the placenta comes to the edge of the cervix and maybe even covers a small part of the cervix. Not uncommon on early ultrasounds. As the pregnancy progresses, there is a good chance that this will resolve. If it is still present as you get farther into the 3rd trimester, then it becomes less likely that it will resolve, and a csection may be necessary. ...Read more

What is placenta previa?

Placenta over cervix: Placenta previa is a complication of pregnancy where the placenta is covering the opening of the uterus called the cervix. It occurs in 1/200 pregnancies more commonly in patients with a previous c section. If diagnosed in early pregnancy it may resolve before delivery. If not a C-section will be needed. It can cause painless bleeding often requiring bedrest. ...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

How long does bleeding with placenta previa last?

How long does bleeding with placenta previa last?

Varies: Placenta previa is a condition in which the placenta implants directly over the cervix and blocks the birth canal. For this reason, women with placenta previa require a c-section. Since the placenta is exposed more, it is more prone to bleeding as well. Bleeding ranges from continuous or occasional spotting to torrential hemorrhage that could threaten the lives of both mother and baby. ...Read more

Why is the bleeding painless from placenta previa?

Why is the bleeding painless from placenta previa?

No contractions.: Because the bleeding does not involve the contractile part of the uterus, only the placenta over the cervix. The placenta is devoid of innervation, therefore the mother does not experience pain in bleeding previa unless preterm labor is also present. ...Read more

If I have placenta previa, when am I most likely to bleed?

If I have placenta previa, when am I most likely to bleed?

Third trimester.: Most cases of placenta previa wither resolve or start bleeding by the third trimester (>28 weeks). Avoid all ssris, aspirin-like drugs (nsaids, motrin, aleve, advil) and only take regular tylenol (acetaminophen) during pregnancy. Avoid intercourse and heavy lifting/exercise until delivery or resolution of your placenta previa. Serial ultrasounds with an experienced maternal-fetal medicine specialist are warranted! ...Read more

Is it abruptio or placenta previa that bleeds when placenta is low?

Is it abruptio or placenta previa that bleeds when placenta is low?

May be both: A previa is usually painless bleeding when the cervix is changing (dilating) causing bleeding from torn vessels being sheared off. It is a type of abruption although any bleeding from a detaching placenta is strictly called an abruption. These are usually away from the cervix and can be associated with cramping, pain, or heavy bleeding. If you have a previa, let your doc know if you bleed. ...Read more

Yes: There is no surgical or mefical treatment yo correct placenta previa however sometimes the placenta can change or move so that it no longer overlies the opening of the cervix if you have true placenta previa it needs to be closely monitored especially the closer you get to going in labor as at that time your cervix will dilate and can cause severe bleeding. ...Read more

Are there lifestyle changes that really make getting placenta previa less likely?

Are there lifestyle changes that really make getting placenta previa less likely?

No: The location of the developing placenta inside the uterus is a random fertilized ovum implantaion event. Placenta previa occurs when implantation occurs low in the uterus by the cervix and "overlaps" the cervical opening (canal) which is more common in women who have had previous children than those who have not. ...Read more

My ob says that having posterior marginal placenta previa is good news rather than it being anterior. Is that true?

Yes: Placenta previa is never good news, but the cesarean delivery is easier if we don't need to deliver through the placenta. An anterior placenta previa for someone with a previous cesarean section can be a very difficult delivery.
You will want to recheck the placenta position closer to term if this was seen on an early sonogram. ...Read more
