Did any of you ladies have a bloody show?

Ni

I had a cervix check two days ago, Doctor said I was thinning but not yet dilated and that my cervix was soft. I just was having sex and looks like bloody mucus in my underwear. I also was having bad back cramps yesterday and last night light contractions that were far apart so I didn’t worry. How long after losing bloody show do you expect to go into labor?
