Have plenty of warm water and gargle with warm water as well. You can see a general physician for this but do update them to prescribe medications which are safe for Pregnancy.

Thanku so much mam yes there is a head nurse there but she was delivering a baby thn she did call back and asked me to consult gp

Hi Tanvi. Ask the clinic to connect you with another doctor. You need to have a contact for emergency. Meanwhile for your congestion please do steaming and gargling with warm haldi and water. Take care
