Don’t know what to do anymore

Me and my fiancé have been on a fertility journey for about 7 1/2 yrs now and feels like we not getting anywhere I went threw a surgery where they did ovarian drilling which is supposed to help me have a period and so on but nothing yet ... pcos is just making it hard i haven’t had a normal period since I was in my early teens and I’m lucky if i get it but in the last 2 yrs I haven’t had a period I’m about ready to give up on this whole fertility thing
