IRREGULAR PERIODS, 2 IVF FAILED

Hi Im 33 I have PCOS, I get my periods very irregular ( every 2 , 3 ,4 ,5, 7 moths) I had a tumor removed from my left ovary, my right fallopian tube is clogged and I had uterine scrapping when I was 21. I already had 2 IVF’s , 3 IUI and they all failed. I had a hysteroscopy and

apparently everything inside my uterus is fine. I feel sad I try to be positive but Sometimes I can’t and I don’t know wha else to do :(
