Hi. I thought I would come back and tell the end of my story (I am the original poster on this thread) in the hopes it might help others.
Unfortunately, my previa remained an issue throughout pregnancy, but I did deliver a beautiful healthy baby boy at 37.5 weeks. There's the spoiler..... all turned out well. :)
At 32.5 weeks I started bleeding and was hospitalized for 4 days. It was not a bad bleed, but was enough to serve as a real wake up call. I received some great advice from a nurse in the hospital.... "you can do everything right and be the best bedrest patient ever and still bleed again." Somehow I got lucky (and I truly think it was luck) and did not bleed again, but the perinatologist overseeing my care determined at 36.5 weeks that my placenta was less than .5cm from my cervix and located anterior. For that reason, a c-section was scheduled for 37.5 weeks. (Note: When I was hospitalized at 32.5 weeks I was given steroids to promote litttle one's lung development. I think this really helped.) Our son was born weighing 8 pounds and didn't have to spend a minute in the NICU. I did lose more blood during delivery than they would have liked, but was able to avoid transfusions and a hysterectomy (possible complications of previa and accreta, the latter of which I did not have).
Thus, I defied the odds in that my placenta did not shift up as is so common, but I did have a healthy child. The 5 weeks 2 days I was on bedrest (not that anyone is counting) were tough but mostly because of my 3.5 year old. I had lots of help between family and babysitters, but she really wanted me to do everything and had trouble understanding that mommy's doctors were making her rest. I also think that my recovery has been a little slower because I was so inactive in the weeks and months before delivery. (The blood loss didn't help either, I'm sure.)
I know that each case of previa is unique and many others have their own stories..... some of which end of with a healthy child and, very sadly, some that do not. My heart breaks for these families.
If you are recently diagnosed with previa, try not to freak out. Chances are very good that the situation will resolve. However, we are fortunate these days to be able to prepare for what can be a tough ride toward the end of pregnancy and a possible early deliver. Be optimistic, yet realistic, and prepare for what might come.
Healthy well wishes to you and yours.
