Sore Throat After Sexual Activity: Not a Pregnancy Sign

Pharyngitis post-coitus is not a recognized symptom of pregnancy.

Likely Causes

• Oral Sex: Mechanical irritation, partner's flora, condom/lubricant sensitivity.
• Reflux: Supine position → laryngopharyngeal reflux (LPR).
• Viral URI: Coincidental timing (rhinovirus, coronavirus, EBV).
• Allergic: Latex, spermicide, seminal plasma hypersensitivity (rare).
• Gonococcal/Chlamydial Pharyngitis: From oral sex—test if at risk.

Pregnancy Diagnosis

Relies on β-hCG detection (urine at missed period; serum earlier). Early symptoms: breast tenderness, fatigue, nausea, urinary frequency—not sore throat.

If pregnancy possible → test. If sore throat persists >5 days, has exudate, fever, or dysphagia → see clinician for strep/STI testing.
