I am pregnant with my third child, my son is almost 7 months and my daughter is 19yrs. Today i went for an ultrasound and was told that there is a large mass beside the baby which looks like ruptured membranes bleeding into the sac. The baby shows a good heartbeat of 102bpm but i am concerened about the internal bleeding. I have not had any spotting other than a slightly pinkish discharge. There has been some very slight cramping. Has anybody ever heard of this before? I have an appointment with my Dr in the morning.
