I just got done with my 4th ultrasound. I've had random spotting here n there my whole pregnancy. Now it happens maybe once a week. They said there is a very small (1mm) collection of fluid/blood behind the placenta. But that it's nothing to worry about. My placenta is over 2 inches away from my cervix so the only cause for the spotting is the pool of blood that may occasionally leak out.. I've never experienced this.. can anyone share their stories? Please? She's 14oz!
