Mucous plug loss??

Ok this goes right into the TMI category!!
Y'day I lost a large(length) of my hand & the width of a finger & a bit, mucousy, brown stringy, blood tinged thing. I went to the hospital again as I have vasa previa & I'm 26 weeks pregnant. One of the nurses said it looks like my mucous plug might be breaking down & another said no she had no idea what it is. my cervix is still looking closed on a scan & I have to see my OB on Monday again for him to check my cervix again. We haven't had dtd because of the vasa. But I have a had a couple of way-to sexy dreams that have resulted in a big O or two. Could that affect my cervix( I was to embarrassed to ask the nurse or doctor). Also has anyone else's started to break down or lost their's early?? When did you then go into labour??
Ive got light period type cramps. That if they get worse I have to call the hospital over the weekend.

I didn't have vasa but I lost my plug on a Sunday and had bub the next day at 30 weeks. We hadn't dtd in a week before. Listen to your body. It will tell you

Oh Bex just wanted to wish you well and I hope it is not your mucas plug. Good news cervix is still closed. Hope you get some reassurances tomorrow xxx
