Ovulation and period

Stopped BCP end of Nov 2017.

Period came 4 weeks later in Dec.

January period came 24 days later (this was my “norm” pre-BCP).

Positive LH surge with opk on CD17.

New predicted period: 32 days.

Is this normal? I thought I was returning to my 24 day cycle but ovulation was a lot later than predicted so I’m wondering now if they will always be longer or all over the place. I know it’s kind of too early to tell, but wondered what other experiences people have had. I’ve never had a cycle that long!
