I have always had tingling around my breast before my menstral but never in the nipple area. For the last couple of weeks Ive had uncomforatble tingling in my nipples and strangly an increased libido. I had a menstrual period that ended on December 19..but then I had antoerh one that ended on Jan 9. Ive been having headaches off and on and irritation. Could I be pregnant and i just had a menstrual preiod??
