I just had the same thing a week ago im 26 weeks. Its def just some of ur mucus plug.
I had this around 25 weeks and 33 weeks. I am now 37 weeks. As long as a very large amount with blood doesn't come out you should be fine. <3
It's part of your mucus plug. Don't worry it will grow back. I had the same snotty discharge 2 weeks ago and I'm also 29 weeks.
