Persistent nasal congestion without fever, sore throat, or body aches often points to pregnancy rhinitis, a hormone-driven swelling of nasal tissues that commonly peaks in the third trimester, while a cold typically brings sneezing, mild fever, and symptoms that fade within 7 to 10 days. Safe relief options include saline sprays or rinses, a cool-mist humidifier, nasal strips, elevating your head during sleep, and staying well hydrated, though many oral decongestants are not recommended late in pregnancy. There are several important factors to consider, including when congestion may signal sinus infection, flu, or a blood pressure concern, so see below for the complete answer before choosing any treatment.
Because third-trimester congestion can disrupt sleep, worsen snoring, and sometimes overlap with conditions that need prompt attention, getting clarity early matters for both you and your baby. Take a free, instant, online symptom check to better understand what may be causing your sniffles and what steps to take next.
