Chances of pregnancy are minimal. You should get periods in 3-4 days of stopping the Regesterone. However these are not regular contraceptives and you should switch over to one for protection as well as periods regularisation.
You can discuss taking lupride injection with your doctor. Though zoladex is more effective and reduces symptoms better. Post zoladex treatment it's feasible to get pregnant. In view of your age and condition, it's better to go for ivf for pregnancy.

If all parameters are normal then pregnancy is a possibility but seeing the history I feel you should go to a hospital specialized in handling complex situations. It is also advisable to go for ivf after an appropriate gap. No point in waiting too long for normal conception.

The beta hcg level at the moment is too low for a pregnancy. If novelon is taken correctly, there won't be a risk of pregnancy. But you should still monitor with another beta hcg after 48 hours to see any serial increase and consult a gynaecologist.

After taking the high hormonal emergency pill one gets withdrawal bleeding 5 to 10 days later,(menas if taken near expected period date it gets delayed) and then a new cycle starts-new counting.
If this does not happen as well as the period is missed then do a pregnancy test.
