could this be my mucus plug?


so I will be 37 weeks tomorrow. since yesterday I have been having this brown discharge that looks preety much like the end of the menstrual flow. already got it checked and everything is fine with the baby. not dialated. today as I whiped it looked like this. could this be a piece of my mucus plug? does it mean that baby is on his way?

sorry if this pic or post offends anyone. not my intention at all
