Help please someone advice

I have been ttcing almost 4 years. I have pcos with irregular periods. These last 6 months i have managed to get them abit more regular. Ive only done ovulation test at the start of trying which i found too confusing and stressful but almost 4 years in and having tried everything from chinese herb,soaks and teas. Acupuncture, reflexology, magic drinks, vitamins, pre seed. Etc to the puttin it to the back if my mind and letting it happen. Nothing has worked! Im at my wits end i thought id giv these another shot and here i am cd22 and still no clear positive! Could it still happen ?
