Talk to your doctor.; You might have caught a bad cold and might be having congestion. Take the right dose of paracetamol

Do your breast feel soft or are they engorged( feel very hard) Symptoms sounds like breast engorgement.

Massage your breast and express milk if it’s hard... aur doc ko bhi dikha lo
