Anyone success getting pregnant with clomid?

Hi. I have PCOS and been TTC for over 12 months. With no luck, i started getting treatment from fertility clinic. Before my treatment, my biggest follicle is only 13.8mm. My period range from 30 to 45 days.

My first treatment this month start with Duphaston to forced having period and start new cycle. I take Clomid 100mg on day 3-7. Had my Tranvaginal Ultrasound on day 11 and i had only 1 follicle bug enough to consider is 15mm only. My RE told me to keep having sex for 1 week and see how it goes.

I don’t have any hope this month. And my RE said to keep trying clomid for at least 6months. Anyone else had succeed on clomid ?
