Diagnosed infertility - what to do?

I’m 27 years old, diagnosed infertility since 5 years ago, tubal factor and only one working ovary. Have gone through 3 tries of in vitro fertilization, one was stimulated, had no response, in all 3 cases I had only one oocyte. AMH 0,91. Do you think I have a chance for a pregnancy with my own oocyte? Sperm quality is good.

Yes, of course, you should fight for your oocytes. There is a variety of minimal stimulations: modified cycles, natural cycles etc. If these methods don’t work, so we will think about donor cells. But you must definitely give your ovaries a chance.
