Sore throat

Has anyone ever gotten a sore throat and fatigue before a bfp? I'm 20 days late and I've taken tests all come out negative. I had one day with really bad heartburn and it made me throw up. I've had a lot of bloating and now my throat is sore and I'm super tired. I've taken 4 tests so far like I said they are all negative. I'm sure I'm not pregnant and just paranoid and just imagining every symptom to be pregnancy.
