I have been off of the depo provera shot for a year and during this time i have not had a period. I recently had unprotected sex and took a home pregancy test 6 days later it came up negative, do I have to wait longer to take another test since I do not have a period? Also how to I get my periods to come again? I thought after a year since being off of the shot they would come but have not. I get symptoms like I am about to have a period, bloating, sweelong of the lower adomen, senisitive breast but still no period.
