I was on depo for about 3 yrs then got off but didnt have a period for about a yr then my periods started and went right back to normal and they were never off till this month now im 5 days late and i took a pregnancy test but it came up negative, soo idk if i should just wait and see if my period starts or take more tests or what to do! Anyone have a similar problem?!
