Did I lose my mucus plug?!

Currently 36 weeks & 5 days and yesterday I had an exam to check my dilation. My obgyn went really deep inside and I measured 2 cm. That was early in the morning yesterday & had no problems with seeing anything wrong but I have contractions and sharp pains in my pelvic area throughout the day.

But today at work, I went to the bathroom because I felt wetness. I wiped and seen that my discharge had streaks of blood in it. Yes, it looked like mucus. Yellow tinted with bright red. Wiped again, and nothing....

Sorry, First time mom!
