Thanks for the query.
Usually after hysteroscopy
one month gap is enough but as you undergone septum resection you can take 2 to 3 months period by that time your endometrial lining etc will become normal.
is a feature of PCOD, for that your doctor might have kept bigomet which is a insulin sensitizer.
If your cycles are regualr you can plan intercourse around the time of ovulation.
If you are having any menstrual irregularity or anovulation
etc, you can go for ovulation induction
