I am pregnant with twins and am about 30 weeks along. I am on bed rest because my cervix is pretty much gone. But I was taking a bath tonight and stood up and this big ball of discharge fell out. If you could roll it up it would have been the size of a marble. I don't remember seeing my mucus plug fall out with my first pregnancy but could this be what this was? Or was it just discharge. My husband and I are very worried but don't want to have to drag out son out if it is nothing.
