When did you regulate again while still nursing?

I got my first period at 5months postpartum.

I used to have 28 day cycles. After birth it started as 41 days, 40 days, then had been 38 days for a few months, at 11months went to 32 days, and now I think it's going to be even shorter again this month. Currently nursing still.

As I nurse less, I will produce less hormones and in turn cycles will become as they were before pregnancy? We are trying to conceive but these wonky cycles aren't helping.
