My experience is from some time ago but thought I would share in case it helps.
We were sent to fertility clinic as my periods were all over the place, anything from 30 days to 6 months. Impossible to know if or when I was ovulating. DH had SA and came back fine. Diagnosis was that I was having probs ovulating, so was prescribed clomid.
Started off on 50mg and I wasn't scanned. Instead, I had to take a wee sample every week, freeze it, and then hand them in every month or so. They would then report back if I had ovulated or not, and amend the dosage if they felt appropriate. It was a fairly reactive process and quite frustrating. Sometimes I wouldn't get AF, so had to get a prescription of xxx (can't remember the name of it - sorry!) to start it so I could start the next round of clomid. To cut a long story short, I did 14 cycles of clomid. I did get a bfp on cycle 8 but it sadly ended up a MMC at 10 weeks. My cycles did end up refaring somewhat, but lasted 35 days or so. I also had a couple of HSGs along the way to check my tubes. I used a Clearblue digital monitor and digital ov sticks to monitor my cycle. And a horrifically sophisticated excel spreadsheet at work - think it was my way of coping.
After cycle 14, they allowed me to try ovulation induction, which was injecting the same drugs as IVF (but in much smaller doses) to stimulate my follicles, and I was scanned every 3 days to track what was happening. When one or two follicles looked 'ripe' I was given a trigger shot to make me ovulate. On cycle 2 it worked, and dd is now 3. We had been ttc for 3.5 years when we conceived.
We decided to try again when dd approached 1.5 but were on our own as no longer eligible for treatment. I lost a stone, used Agnus Castus (some call it natures clomid) to help regulate my cycles, and we conceived after 6 months. Dd2 us now 5 months (and i was 40 when i had her)! I defo feel losing weight and having been pregnant helped right my system somehow.
I wish you the best of luck. I hope it's a short road to success, and that you conceive soon.
