Potentially might be sick. How do I handle this?

Tonight my voice started sounding hoarse but no sore throat. My fiancé asked 2-3x if I had a sore throat after he caught me drinking hot lemon water(I hate tea but wanted something warm that wasn’t hot water) I fell asleep on the couch and just woke up to it starting to hurt a tiny bit.

We’re at his moms where everyone is staying until after new years, his sibling is a hypochondriac(their words) and his grandparents are supposed to come for new years. Idk what to do. He’s 100% going to think I lied to him and I feel bad because It’ll also cause everyone to not be able to come/his siblings go home.
