low fever and headache 5 days post partum?

Anyone have an off and on low fever (just at 100 Fahrenheit) and headache 5 days post partum? I do not think it's worth a call to the docs answering service but am wondering if I should be concerned. My milk just came in and I do have a few ducts that feel backed up but no redness. I had mastitis with my first and felt much worse than I feel today. Also a bit uncomfortable to pee... But everything down there is uncomfortable at this point!
