Following is my reply:1 You might be having polycystic ovaries who generally ovulate late. This needs to be confirmed by scan from your doctor.2 Next time ask your doctor about using gonadotrophin injections which help in growing follicles.3 Your treatment seems to need upgrading. Please visit an infertility specialist.4 GUI has better success rate than trying naturally. Hence, you can consider it if there is difficulty to conceive naturally. I hope I answered your query. I will be available for any follow-up query you have.
