Hi, I am a 27 year old who has been on BC for 7 years, I am very good at taking my BC at the same time everyday. The last 2 months I have not gotten my period, I have taken 3 home pregnancy tests and all have come back negative, I have no symptoms of pregnancy. Do I need to visit my Gyno? Is there something else that may be wrong? I have not had an increase in stress, I have had some gradual weight gain and lack of exercise. Do I need to worry?
