Labor?

Been having early labor contractions at both 30 and 31 weeks. Doctors gave me medicine to stop the contractions each time and also during the 31 week time gave me steroids to help develop babies lungs in case. Well today I am 32 weeks and just noticed a very small amount of what appeared to be mucus plug maybe in the toilet. If there is anyone with experience on preterm labor issues or mucus plugs or anything I would love any tips thoughts or experiences you have for me.

Also not sure if it matters but I have gestational diabetes and this is my second pregnancy. No issues in first of anything at all.
