Thanks for the query.
after stopping the hormonal
pills it will take some time for regularization of the cycles.
The spotting you had could be withdrawal bleeding due to stopping the pill.
So you wait and watch the next cycle.
If the same thing repeats consult gynecologist once and take tablets to stop the spotting and for regularization of the cycles.
After that you can plan for pregnancy
by racking the ovulation and having unprotected intercourse
around that time.
