On January 8th, I performed oral sex on a guy and he ejaculated in my mouth and I swallowed some semen before he pulled out. That following week I had an onset of symptoms that would come in go for the next month or so: sore throat on one side, one swollen lymph node on the side of my neck, post nasal drip on same side as sore throat, headache & dizziness, pins and needles all over my body (this lasted for months but could be due to anxiety/hormonal imbalance) etc. I freaked out and took 3 Oraquick tests at 83, 93, & 97 days post exposure. All were negative. Is this conclusive? Can I stop worrying about false negatives?
