Hi I am 7 weeks 3 days pregnant. From past 8-10 days I feel cough like choked in my throat without any mucus or pain. I feel difficulty in breathing and eating as all time I feel bad smell of mucus in my nose. Dr. Recommended pan 40 but didn't worked well. Due to this I am not taking my meals and this can affect my pregnancy n health. Tried vomiting yesterday and some cough came out. But soon after few minutes my throat as again full and choked. Help me with this. Also taking steam and gargling not that effective. Suggest something helpful in pregnancy
