Periods after depo and cerazette :(

Okay, Well i was on Depo for 3 months (1 shot only) from september 10 - 30th November. I got one period on Depo around the 14th -21st november. I didn't get a second shot of depo I hated it!

Febuary the 2nd I came on my period, really heavy... Normally my periods last around a 7-10 days, this lasted nearly a whole month, it was heavy almost everyday, so I went to a sexual health clinic and they put me on cerazette to make the bleeding stop & it did. Once the bleeding had stopped i went off cerazette. I got a breakthrough bleed march 6th. 2 weeks after stopping cerazette..

(I'VE BEEN ON CERAZETTE TWICE BEFORE AND AFTER STOPPING IT IVE HAD THIS BREAKTHROUGH BLEED EXACTLY 2 WEEKS AFTER STOPPING IT AND I'D '''NORMALLY''' GET A NORMAL PERIOD 4 WEEKS AFTER THAT)

I should have had a period yesterday, I didn't so i took a pregnancy test today just to clarify I werent pregnant.

Can anyone help me, how long did it take you to get a proper period after depo? sorry for the essay ):
