Very short cycles and early ovulation postpartum

After I had my baby I immediately got on birth control, so I technically haven’t had a period or ovulated in almost 2 years.

Recently stopped birth control after my baby turned 1 to give my body and hormones a break.

I’ve had 3 real cycles since stopping the pill.

The first one was 25 days, the second one was 23 days and this last one was 21 days. Each cycle I also ovulated only 3-4 days after my period ended.

Is this normal? Has anyone else ever experienced something like this?
