Could this be part of mucus plug?

Rosalie

I was having contractions a day and a half ago and only 1.5 cm dilated, so doctor doesn’t want to check me again until Monday morning but could this be part of my mucus plug? First baby, so I’m not sure 🤔 I’m due July 23rd, but doctor wants to induce me Tuesday the 16th at 39 weeks, if baby doesn’t come on her own before
