Discuss with OB.: Flying is ill advised during pregnancy with risk for serious bleeding as is the risk with placenta previa. It's a big risk, should anything happen, you won't be able to land in time to save you or the baby in the event of bleeding. Repeat US will help determine if the placenta changes position, but an abundance of caution is best in this case. ...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

Can you have sex with a placenta previa?

Be cautious: No! A placenta previa can be dangerous and result in heavy bleeding. Anything that could disturb the previa should be avoided, like sex, fingers, really anything in the vagina. A previa can resolve over many weeks, so make sure your doctor is checking to see if it is still there. Until then, I would wait. Good luck! Dr S ...Read more

Can placenta previa be corrected with bed rest?

Can placenta previa be corrected with bed rest?

Not really.: If the diagnosis of placenta previa is made before 20 weeks, some women experience resolution of the morbid placental implantation with time - bedrest is not correcting the problem. As the uterus and the fetus grow, they pull on the placenta and stretch the lower uterine segment to "move" the placenta out of the way and allow for vaginal delivery at term. ...Read more
