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. ...Read more

Had inc. placenta previa at 16 weeks, moved up around 21 wks (3cm+) now at almost 32 wks u/s showing 1.5cm fr cervix. why did it move down again?

Doesn’t move: The placenta does not actually move. It is attached to the uterus. As the uterus grows the placenta can be pulled safely away from the cervix. In some cases it does not. It just depends on where the placenta is attached. In general it needs to be more than 2 cm from the cervix to permit vaginal delivery ...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

I had a 2nd csection 10 weeks ago (previous was 2 years ago). During surgery they found i had placenta previa & had to cut through the placenta.  i h?

What is the question: I do not know what your situation was , but almost always placenta previa should be diagnosed before you had the csection by an ultrasound , all of my pts get at least 4 ultrasounds , the last one being 34-36 weeks which also checks the location of the placenta, because if u had a previous csection a placenta previa can often cause a placenat accreta which can cause big problems , glad u did ok. ...Read more

What can you tell me about placenta previa?

Attached over cervix: Placenta previa is when the placenta attaches low inside the uterus, near theopening of the birth canal/cervix. This can cause problems during the birth process because when the cervix starts dilating it could tear the blood vessels in the placenta, depriving the baby of blood and making mom lose too much blood. To be safe, many ob's recommend a c-section instead of vaginal birth. ...Read more
