So I'm now 3 weeks late with AF, blood test came back negative even though I had faint lines on a few tests which others could see so I wasn't going crazy! Has anyone else had this? I was on the depo but only for 6 months and I had a period every month whilst on it. Was due a shot in August but didn't have it done as I thought I was pregnant due to the faint lines. Just want AF to hurry up now so I know where I am!!
