Spotting at 37 weeks..HELP

So I’m spotting, and it had to be right AFTER I saw my doctor this morning🙄😑 something always happens after I leave her. Anywho, it was just a spot, very light light red, almost pink. Then I changed the pad and now it’s like..more spots..? And it went thru the panty liner at the bottom so I saw the light light pink red. So weird. I showered and I will see if more comes up, if so I’m calling the doctor tomorrow. Idk what it could be..also I am cramping and have been contracting all day.
