Really messed up periods after coming off mini pill

[incendio]

So i was on cerelle for about a year and didn't have any periods while on it. I came off it exactly a year ago and my periods haven't come back properly since.

I've had 2 periods, one in feb and one in April. I've had sore breasts for about a week now and a bit of cramping but still no period.

Has anyone else experienced this? I've had a look online and most people seem to be saying their period went back to normal within 3-4 months.

Before I was on cerelle I was taking rigevidon for about a year and a half and I came off that because it was making me very depressed and angry. I haven't used any hormonal contraception since I came off cerelle.
