I am 22 years old and had a baby 7 months ago.I have been been on my period since the 22nd of Dec. I have experienced some light and heavy bleeding in no particular order. I haven't been on birth control in years and haven't changed my diet or activity level. Over the last week I've been extremely nausiated, had bad chills, bodyaches( especially in my back and legs),belly cramps and headaches. I'm wondering if this is all related or possibly a long lasting virus and hormone imbalance. I greatly appreciate any input.
