Hi Dr., I recently had the birth Control Implanon removed on June 28, 2012. A week after having ir removed Ive had unprotected sex. Three weeks later I started deeling light headed, increase in apetite, and sore breast . I took a pregnancy test and it was negative. It is now August 10, and I still have no period, and now Ive been extremely tired and peeing more frequently. Could I be pregnant?
