Mucus plug

I’m 30 weeks 1 day and yesterday I lost a tiny piece of my mucus plug and my significant other was freaking out about it cause he googled it and it said If I lost some before 37 weeks I should go to the hospital because it could be a sign of preterm labor. I reassured him that it grows back and it doesn’t mean anything after about 30 minutes he finally calmed down. Well I told my neighbor who is a really close friend of mine and now she has me convinced that I’m going to go into labor within the next couple of weeks. So my question is: I wasn’t wrong and it does grow back right? And it doesn’t mean I’m going to go into labor anytime soon?
