Depo injection

So September 2017 I stopped the depo because it takes up to 18 months to get out of your system and then started the pill straight away. August 2nd 2018 I came off the pill all together 10-12th August I had a very small wipeable bleed (not enough enough for a pad) so yesterday I went to the doctors and I was told I had to wait for a year for my period to come back before doing anything but have sent me to have a ultrasound and bloods to check my hormones, have anyone else had any problems with regulating your period after the depo? Stories would be appreciated x
