Hello, I have gone through your query and understood the concern. Please see a physician for a proper clinical assessment and treatment as any form of self-medication is to be avoided in pregnancy. You can have saline water gargles, steam inhalations, apply cold rubs like vicks to the throat, back and chest to relieve congestion. Antihistamines and paracetamol are usually prescribed. Antibiotics can be used if there is a suspected bacterial infection. Please take lukewarm water to drink, maintain good fluid and electrolyte balance and take good rest. Usually, the pregnancy is unaffected with milder infections. Do not worry. Inform your consultant of the infection for further suggestions. Hope this helps.
