I didn't have it but my sister had partial previa (not the same I know) and it was scary enough to figure things out. The questions that were important to her were about the likelihood of the placenta moving far enough away from the cervix for her to deliver vaginally. They have to measure and it has to be within a certain amount that somewhat varies based on a providers comfort level. She was put on partial bed rest and complete pelvic rest. If she had any bleeding she was to let her provider know and any bright red blood or larger amount she was to go into the hospital immediately. She did have two times of bleeding that required going to the hospital and one-two weeks of spotting that had to be monitored. She had a few ultrasounds but there was no point to do it if she wasn't bleeding a concerning amount and wasn't dialating for delivery. A lot of her bleeding was the placenta moving away from the cervix as her uterus expanded. It moved enough that she was allowed to have a vaginal birth but was not able to do a homebirth. Her doctor was prepared for a possible hemmorhage but the birth went smoothly at 39 weeks and she had no issues with the placenta. It made for over 20 weeks of higher than normal stress for her pregnancy but birth and postpartum were a lot happier.
I would ask what amount of bleeding is ok if any and when to go to the ER?
Who to call while on the way so they can be prepared?
What is the likelihood of having to stay overnight in the hospital if you have a bleed? My sister had to and it was not expected really.
If a vaginal birth is still something they can consider, or wait and see about? How long to they, and you, feel comfortable waiting before the c-section vs vaginal birth decision is made? What is the cutoff date?
I would ask for specifics about bed rest. My sister did the best she could but her son was 18 months when her second was born. I was there to help every day but there is only so much sitting on the couch one can do with an active toddler- who, by the way- nursed all through the pregnancy and no doctor was concerned at all about that.
I hope that is somewhat helpful. I know it is not first person experience but I was at a lot of the mw appointments and did a lot of processing with her. Hugs mama, you still have a long time for this to possibly move, and if not, there are many that can support you with c-section recovery.
