Depo worst mistake of my life

Rebecca

So iv been on depo for 5 years my last shot was 13/04/18 so it ran out in July, I had constant bleeding from the 3rd of July to 22nd of November, at this point I liter begged the doctor to give me somthing to try regulate my cycle, so she gave me norethisterone for 10 days that ran out on 2bd ov December, so now iv had no period since the 22nd of November, iv got pregnancy symptoms but getting negatives on the test , I ovulated on the 16th of December but just never got my period

Did anyone else have a similar problem?? How long did it take to get back to normal?
