Help!!! Long cycles are messing me up!

My cycle does whatever it feels like! We are TTC and it is really making it difficult. We started TTC in May I stopped the pill after years on it, my cycle was 52 then 49 then 35 days. Then I had a M/C at 5 weeks & my cycle after that was 89 days. I am now on CD51. When the longest happened (89 days), I had to go to the hospital because of really bad cramps and nausea. Dr said it’s because the uterine lining was building up for so long. Since the MC, I get a lot of mild ovarian cramps on and off at every point of my cycle. I have been to the gynaecologist for assessment, hubby and I both got tests done. The dr just said all the tests are within normal range, there just seems to be a delay in the ovulation process and he wants to wait for AF to come to get me on chlomiphene. I am still wanting to try in the meantime but I am very very frustrated because I can’t seem to track or time anything with no pattern emerging. I need serious baby dust guys!
