Hello, i'm 26 unmarried virgin girl. 2 years back I had laparoscopic surgery for endometriosis chocolate cyst 9 cm. And i'm suffering from endometriosis. After surgery I took digest 2 mg twice a day for 6 months, but while taking this tablet I suffered a lot with stomach pain, spotting, break through bleeding and vomiting. So doctor suggested ethinyl estradiol (0.02 mg)+desogestrel. (0.15 mg) ocp back to back for 63 days once per day. After 63rd day I stopped this tablet, so that my periods came. From 3rd day again I started tablet for 63 days. Like this for 6 months. Then my doctor told me to take this tablet for 42 days back to back. Till may 2021 I took this tablet like this. But on may month I suffered with severe bleeding while taking that ocp tablet. To stop bleeding I took norethisterone 5 mg. My question is shall I take norethisterone 5 mg once a day continuously for 42 days cycle for 2 years? (like ocp). And what are the side effects on this tablet? Is there any serious side effects on this tablet? Note: don't suggest ocp combination pill again, bcoz it is not suitable for me.
