Mucous plug or normal discharge?

m

I’m 22 weeks and extremely paranoid about everything lately. My water broke with my son at 22 weeks so I’ve have horrible paranoia and anxiety. Anyway this morning I wiped and there was a small bit of mucousy discharge on the toilet paper. Now I’m worried that it could be bits of my mucous plug. I know it can grow back but considering my history it still really worries me. Is it normal to have mucousy discharge at this point in pregnancy?
