I was a few days late for my period and then I started. It is a normal flow and color period and is still going on 3 days later, but I started having extreme cramps and pain around my back where my kidneys are. I have every symptom of a kidney infection including fever and nasea. All I want to know is there any way I could be pregnant or am I in the clear? Is it possible to be on your 3rd day of a normal period and still be pregnant? All this kidney infection stuff was freaking me out.
