Hi, about 10 days before my period I had some spotting. It was dark brown but only lasted a few hours. Now 6 days before my period i’m having a light brown muscus that also just lasted one time. I’ve been very exhausted lately, loss of appetite, moody, and not many cramps. I have taken 5 pregnancy tests & all have turned out negative but it could still be too early. I take birth control religiously & have been for years. Could I be pregnant?
