Spotting a week after af ended.

Cheyenne

My periods have never been regular I can go 2 or 3 months without a period which my dr says could just be normal for me... in october I had a period lasted 8 days then 2 weeks later started my period again and lasted 10 days now a week after it ended I had spotting for a day could this be another period or ovulation? I made an appointment to see what is going on. I just want some advice please maybe someone has gone through this also? I have a 2 year old daughter and have been ttc since before she was 1.
