I'm pregnant with #2 and have felt this strange pregnancy symptom for a while and wanted to see if anyone else has heard about it... It hasn't really given me a reason to worry, hence the reason I forgot to mention it at my last ob appointment.
I'm feeling a strange pulsating sensation near the bottom of my pelvic bones. It's almost as if there's a tube of some sort with a pulsating liquid running through... perhaps even like a "purring" sensation (this sounds really weird, I just can't think of another way to describe it). I feel it when I'm sitting down or standing up...I've tried timing it with my pulse and sometimes the pulsating feeling occurs every 6-10 heart beat pulses (usually when I'm standing) or every half second (usually when I'm sitting), but longer than a single heart beat.
Wild, uneducated guess...could it be the pulsing umbilical cord I'm feeling? I didn't have this sensation with my first pregancy. Should I be worried?
