HELLPPP

My bf and I had sex on the 16th of this month, I was at my peak of ovulation. Panicked and took an emergency contraception 4 hrs later. Googled it and says that it’s possible it won’t work due to ovulating. It’s been 5 days and the past three days I’ve been crampy, tired, woke up at 3 am to major back cramps, bad acne, tender breasts and I’ve been very hungry and up until the past three days I hated chicken and now I eat chicken everyday. I’ve been peeing a lot a lot a lot! And today I developed a store throat and the whole side of my neck is swollen, i read that some people have had this symptom and it turned out they ended up pregnant. My period isn’t due until the 30th and some website “when to test “ calculators say I could test as early as up to tomorrow with clear blue . And 6 days for one step. What are your thoughts. Has anyone who’s been pregnant had these symptoms or taken an emergency contraception? I don’t want to be pregnant
