Hey, sorry to hear what you are going through.
I was TTC for 2.5 years before my BFP. I thought I had PCOS (thanks Dr. Google), the doctor said "although you have some of the symptoms, I dont think you have PCOS". It wasnt until my 12 week ultrasound that the sonographer said "you have PCOS dont you?". I told her what the doctor said and she said "actually, see here, they are little cysts in your ovaries". So more than likely I had/have undiagnosed PCOS. My cycles were 40 days to 200+ days. I tried 1 round of Clomid which failed, then at then end of that cycle, I had a UTI and the doctor suggested I take a break while on the antibiotics just in case. So the next cycle without any Clomid I waited and waited for CD 36 (when the doctor suggested to take the provera to start AF), but then I gave myself until CD 39 to try and get AF by itself. I took a pregnancy test of CD 39 and it was negative. So I started taking the provera, waited for my period which didnt come. I took a pregnancy test and low and behold it was positive. At my dating scan, I found out I ovulated on CD 39. The doctor who prescribed the Clomid, his instructions were to DTD on CD 14... I knew people ovulated at different times and ignored that part of the instructions, but I really didnt think I could ovulate THAT late in the cycle. I had also given up at the time on the cycle and was waiting for AF. I was actually looking forward to the next cycle and starting Clomid again.
During my TTC journey, I have seen people on huggies, TTC, fall pregnant, have their baby, then TTC for #2 and fall pregnant again. Its really hard to watch really. I always hoped I would get pregnant, but I thought Id be one of those people who couldnt get pregnant, or tried for years and years and then gave up. Now that I am pregnant, I think I am still in shock (at 33 weeks!) and most of the time I say to myself "I cant believe I am pregnant, I cant believe there is a baby in there".
All I can say is that every time I failed, I let myself grieve and then I looked forward to the next cycle (mind you this was quite hard with long cycles). If you put the focus on the next cycle, rather than the failure, you have something to focus on and look forward to. Well thats what I found anyway.
I really believe it was just pure luck and perhaps the Clomid in the other cycle stimulated something in my body.
You will get there, you just need to keep plodding along. Others have tried herbs and swear by acupuncture but thats not for me, but it may be for you?
I wish you all the best.
