question: Since December I have had the flu 4 times already (so practically every month), lasting anywhere from 5 days to 2 weeks. Every time I have had a fever and backaches. The doctors says this is normal and I should not be worried, but last month and this time there is a heightened sense of smell that makes me extremely nauseous. I get my periods regularly and don't believe I can be pregnant. Why am I getting the cold so often?
