I’m hopeless

My husband and I have been trying since January. I have PCOS. Ive know I’ve had it since I was 16. I’ve been on letrozole and clomid. Never ovulated. I’m so defeated and at a lose of what to do. I have an appointment with a fertility specialist in August so I wanted to keep trying meds to ovulate. But I can’t get a positive opk test. I’m on CD 16 right now of 100mg of clomid. Ladies that didn’t respond to clomid or letrozole- what was your next step?
