So confused!!!! Help or any suggestions

I’ve been taking clomid 100mg for 5 months, I’m on my second cycle of metformin as well. I was diagnosed with pcos. I tried to conceive naturally for 6 years. My first clycle of clomid was 50mg and I did not ovulate, the doctor bumped it up to 100mg and I FINALLY OVULATED!! I was so excited and it gave me hope. Well 5 months later and still nothing. I’m about to go on to my 7month if clomid and second month of metformin together. I’m confused because I do usually have regular periods and always have menstrual symptoms such as mood swings, always sore breasts a week after my ovulation date. Still nothing 😞 im not sure what’s going on if I’m ovulating and having regular periods?! It’s really heartbreaking for me and my partner. The next step is

IVF

and it cost so much.
