Does Placenta Previa Cause Preterm Labor
Diagnosed with partial/marginal placenta previa (25 wks). Precautions? Worried about preterm labor, placenta has not moved up since 17 wk scan.
Try to relax!: It's still fairly early to be worried. Most patients with marginal placentas deliver vaginally without incident. If this is your first pregnancy your lower uterine segment will not soften until fairly close to term so the placenta may appear to be low until fairly late. As long as there isn't significant vaginal bleeding you shouldn't worry. ...Read more
Bleeding and Cntrxns: 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
Cesarean by 36-37w.: Placenta previa can lead to preterm labor, so I would recommend prelabor (i.e. Shceuled) cesarean section by 36-37 weeks.

All this shoudl be done in a large hospital. The infant should do well regardless. ...Read more

Is sex safe in the third trimester? Can it cause preterm labor? What positions are best? Is oral sex ok?
It can.: Amniocentesis involves introducing a fine needle into the pregnancy sac to retrieve some amniotic fluid for fetal dna testing. That technique had inherent risks for complications, including preterm labor and preterm premature rupture of membranes. The risk for any of these complications to occur is <1%, but is real and devastating if they do occur. ...Read more

Such conditions include: infections, poor growth, placental failure, bleeding, too much amniotic fluid, multifetal pregnancies, trauma, fetal anomalies causing hydrops or heary failure, etc. Most of the time there is no diagnosis and preterm labor is "idiopathic". ...Read more

I had a micro preemie at 24 weeks due to a uterine infection that caused preterm labor. How likely am I to have another preemie?
Varies: If it was truly due to an infection and that infection is treated and cured, you would be at no higher risk than usual. However, if there were other contributing circumstances, like early cervical shortening, any abnormalities of uterus, then the risk could be a lot higher. It's an excellent thing to talk to a maternal-fetal medicine specialist about and what you can do pre-pregnancy to prevent. ...Read more
Is there fact to too much rubbing belly in first trimester cause increased body temperature that may provoke miscarriage or preterm labor? Doc said so
No: Rubbing the belly surface won't increase one's body temperature inside. The skin may get a little warmer where one rubs. Nothing unusual happens to the baby, because the baby is inside, at a stable temperature. So, if any baby problems arise, they are not due to rubbing the belly surface. ...Read more
