i was on the ring birth control. i stopped using it because it made me extremely moody and made me depressed. i stoped using it about 2-3wks ago, and im currently not using protection. my period is on time and always light, but now its on time but lighter than usual, my breasts arent sore but they feel somewhat tender. i have to urinate more than usual but i do drink alot of fluids. im always tired because of my work hours. i work in the evening and dont get home between the hours of 3am-430am. could i there be a possibility that i might pregnant?
