Yes it is okay to have Primolut tablet after I PILL
Usually you should start progesterone
3-4 days before the expected due date to postpone the period.
But since you took I PILL in the first half of your cycle, probably your period will be preponed by few days. So discuss with your doctor and start taking the progesterone from 10th onwards. Take the tablets until 24th. You should get your periods within a week after stopping medications.
I hope I have answered to your satisfaction.
