Normal?

I went in for my weekly appt and my doctor checked me for the first time. I’m 37 weeks and 4 days. She said I’m 1.5 centimeters dilated, 70% effaced, and baby’s head is right there. She said she thinks he can come within this week. Well that was this morning. I did spot a tiny bit after but then it stopped. Now it’s almost midnight and I went to go to the bathroom and this happened. There was more of it in the toilet. Normal?! Maybe just part of my mucus plug? I lost it already but i know it regenerates.
