Thanks for all your thoughts today-
I was really pleased with the cardiologist--he knows a lot about the link between heart issues and pregnancy, and was able to give me enough information to feel at ease about what is going on with my ticker.
I have what is called PVC, or premature ventricular contraction. Not serious, though--just the medical term for why my heart is skipping beats. He estimates my heart has grown about 30% and is definitely pumping lots more blood through my system. All my pulse points checked out OK, and my blood pressure is still good. No need to wear a monitor right now--just have to pay close attention to the frequency, and if my heart rate actually starts to accelerate and stay accelerated for a period of time.
He said with the combination of the PVC and if my previa persists, Im most likely looking at bed rest again in the near future--so now Im doing my best not to stress about getting too much done in the next 4-5 weeks (when I get checked for the previa again).
Speaking of previa, I made the mistake of posting on a board today, asking if anyone had complete previa and then had it move, and all the responses were so morose: "ooo plan to bleed and be on bed rest with a c-section in your future." Not doing THAT again....sheesh.
