jelly like discharge

Im only 12weeks and i had this jelly like. i had sex 2 days before this. im not sure if this is the balance sperm or something more serious like mucus plug. sorry for being paranoid coz this is my 4th pregnancy after 3 losses within 2 year. 😔 also i did experience this jelly like discharge with no blood at 18 weeks pregnant in 2023, and 1.5weeks later i gave birth to a 19 week old baby who didnt survive.
