Nauseated & still bfn’s

I’ve been taking pregnancy test because I’ve missed my period (9days late today). At first I took a blue dye and there was a faint line. I was afraid it was a Evap line so I went and got a pink dye test. Took this morning and nothing. Was negative. I was on depo I quit and didn’t take my last shot in feb like I was suppose to. I had a regular period is March, April and May but not this month. I feel like my appetite has picked up big time and I’m staying so sick at bed time.

I’m just so confused. Where is my period if I’m not pregnant & ive been having regular periods again?

Any comment?
