What is this?

TMI!! Don’t come for me. It’s my first pregnancy and I’m curious, Everything scares me because I want a healthy baby.

What can this be? I’m 38 weeks pregnant and this type of discharge keeps coming out little by little. It’s kn my panty liners and when I wipe it goes on the tissue. I have searched for pictures of mucus plug and it doesn’t look like it to me. Can it be an infection??? It is yellowish on the pad and tissue even though on my hand it looks white/clear. It is odorless.
