After sex i had some vaginal bleeding.  Mucous and small clots of blood come out. I have filled 2 panty liners in 1 hour.  Ive had about 30 contractions since 7:02 and it is now 8:30. At 3mins apart lasting a minute long...  Should i go in or not?    Really dont want to wake up my SO Since its his day off but could this be Dday ?!?!?
