Got pcos and period started again 😢

I'm currently taking clomid and this was my first month taking it while I had 3 month off due to not getting a hospital appoitment for ages ☹️ but I came in this morning why can't I just fall pregnant like others being trying for 3 years now only got diagnosed last year but told my bf if I can't give him one he could go with someone else which he said e lived me and wouldn't ,but just think what else can I do to help me fall pregnant Iv got pcos and just feel like I'm never going to get pregnant the hospital said I should fall pregnant on the tablets as everything else is normall but when any success storeys need some uplifting happiness as just feel depressed all the time 😢
