Do you feel like ovulation test are a waste of money? well at least in my situation should i use them?

Me and my hubby have been going to a fertility specialist for a year I was on clomid until the dr noticed I should have a laproscopy, tubal dye infusion, and a hystopinogram and discovered my tubes were blocked completely ....they were uncloged and now I'm suppose to be ok....that's was my only problem....now I'm on femara this time around I started in march I didnt have any luck my dr told me to start testing while I'm on the pill? This has been a very long process.....I'm open to suggestions stories anything!!!!
