I am SO worried!

I have FOUR bumps inside my lower lip! AND the area between my vagina and the anus has been swollen since yesterday. This morning I noticed TWO BIG ASS white bumps on the swollen part and I am BEYOND scared. I’ve only been with one sexual partner, my fiancé. But before we got back together and got engaged, we took a break in which he caught Trich and unknowingly gave it to me. I moved passed it because he caught it way before we got back together and he didn’t know. We decided to move forward. We both took our prescriptions. It’s been over a year now. But if this is something SERIOUS that I caught from him, *something new & recent like he had cheated*, then I’m completely done. I am stressing so much. I’ve also been feeling sick, my entire body hurts. I have cramps. Covid test was negative. I called out of work to go to the emergency room. We last had sex on Sunday (oral was involved). Wish me luck PLEASE!!
