So I’ve been reading that this is considered kissing disease? Mononucleosis?? And is this an STD?!!! But it says that symptoms appear 14 days after exposure

I made out with a guy exactly 1 week ago (Friday august 2) I started with symptoms 3 days after

By Monday I started feeling a little soreness and drowsiness

Then Tuesday it was much worse. Joint pain and watery eyes. Felt really hot but had no fever

Then Wednesday seemed to be better but now it’s Thursday and this soreness is bad. I don’t. Have a cough or body aches but it really

Hurts to swallow food or saliva. It feels like I have a rock there

We had sex with a condom too which he didn’t ejaculate but now I’m wondering if it’s due to him

And I kissing ????

Update: saw the back of my throat and saw like a white rock? Also I just gargled salt water and it feels better ….
