Second round of clomid

Hi guys , I’m on my second round of Clomid ttc #2 , af is very irregular for me sometimes lasting weeks and sometimes not coming for months , I was diagnosed with pcos when I was a 19 {23 now} & told it would be hard for me to have a child. I had my first daughter while taking bcp & missing a couple doses by accident. The first round didn’t work but I did end up getting af which was good news for me it’s rare that I get it 2 months in a row ! So here’s hoping the second round works for me , any tips ? Success stories ? I’m doing cd 5-9 .
