Question 1

if a woman has placenta previa from a old birth scar is it less unlikely to move?

Accepted Answer

Previa: Can be dangerous. You need obstetrician with experience and well equipped hospital for delivery.

Question 2

diagnosed with placenta previa at my 32-week scan. is there still a chance that the placenta will migrate? im praying for a natural birth but want to be practical as well.

Accepted Answer

Unlikely: If diagnosed in early pregnancy, a placenta previa has a chance to resolve on its own. Diagnosed at 32 weeks, it is most likely fixed and you will need a C section to prevent life threatening bleeding. Although not "natural", a C-section has many benefits for the baby including less skull deformation, and fewer birth injuries such as asphyxia, shoulder dystocia and fractures.

Question 3

i had placenta previa with my 2nd baby its been 18 months since the birth im now useing implanon for contreception. my period. blood smells bad?

Accepted Answer

Bacterial vaginosis: Vaginal odor would be unrelated to your delivery 18 months ago and unrelated to implanon. This sounds like infection and most likely bacterial vaginosis. Blood tends to make the odor worse with this infection. Treatment is antibiotics so you will need to see your obgyn for testing and confirmation.

Question 4

im covid positive and 9 weeks pregnant. have had fevers up to102 for a week. ive read covid can cross placenta and cause birth defects. what can i ask my ob to monitor and can this cause cerebral palsy etc? worried because all infections dangerous?

Accepted Answer

: The data thus far shows that healthy mothers with COVID 19 do not significantly place the baby at risk. If you are short of breath, please see the Emergency room. Keep well hydrated, see your OB by video and treat fever. Request information regarding CDC and other guidelines.

Question 5

why does placenta previa cause cramping and bleeding?

Accepted Answer

Bleeding: Placenta previa is the placenta implanting over the internal opening of the cervix, and is a very serious problem.  It will necessitate you having a caesarean section, as you will not be able to have a vaginal birth.  As to bleeding, it can be very serious, and should be reported to your doctor immediately.

Question 6

can marginal placenta previa cause placental abruption? what are the statistics on marginal previa moving after 20 weeks?

Accepted Answer

Cervix and placenta: Will move apart
as a balloon expands, (uterus), points on the balloon move apart, this will likely occur as the uterus grows, if no bleeding, little risk of harm. Ask your doctor to be sure. 
Previa can create a type of partial abruption, along the edge of the attachment.

Question 7

how does placenta previa cause preterm delivery?

Accepted Answer

In placenta previa,: the placenta either partially or completely overlaps the opening of the cervix.  As the cervix starts to dilate, the blood vessels of the placenta are exposed and start to bleed, and if the bleeding doesn't stop or is very heavy, the baby needs to be delivered immediately or may not survive due to blood loss.  The cervix softens several weeks before  due date, so important to monitor carefully.

Question 8

can placenta previa (abrupto @34wk but wasnt seen til 36w) cause postpartum issues? excessive irregular bleeding, pelvic sensitivity?  i am 7month pp

Accepted Answer

Should not: Causes issues with pregnancy, labor and delivery but 7 months later should not be an issue.

Question 9

with anterior complete placenta previa and 2 bleeds (1 warning, 1 massive) what are the chances of the placenta shifting with the uterus after 24wks? and possible cause of constant dull aches and jolts in pelvis area. also have short cx

Accepted Answer

MFM evaluation: Consider asking for a referral to a maternal fetal medicine specialist. Your situation sounds quite high risk especially when you use phrases like massive bleeding. Your doctor may want to consider keeping you in the hospital now that the baby has reached viability.  The chances of previa resolution will vary depending on the exact location and will vary from person to person

Question 10

the answers indicate placenta previa is not hereditary. how conclusive is this? an aunt, two cousins and i experienced placenta previa with four dead infants and only my child survived. all four of us are from one branch  my mothers mothers mother?

Accepted Answer

: Having 3 members of a family tree die in separate car wrecks doesn't make the issue hereditary. The suspicion of and investigation for a hereditary linkage involves detecting an issue in tens of thousands of family groupings to come up with an assumption. When it does not occur more than sporadically, the linkage is not assumed.
