Help please 😓

So after having sex yesterday I went to the bathroom, peed out some “semen” and went to bed. Woke up today and i have like snotty discharge? Tmi sorry. Now tonight it’s like jelly? I’m so so so worried it’s my mucus plug but I have no idea what it looks like! I’ve never had this discharge in my pregnancy and I’m 19 weeks... help please idk what to do and my drs office is closed until monday. Idk if this is normal after he finishes in you??
