Feeling Discouraged

I have been feeling super discouraged lately. We have been trying since early November with no luck. I was put on Metformin in March and started Clomid this cycle. How long were any of you ladies on Clomid before becoming pregnant? I was diagnosed with PCOS because of irregular cycles and I have hypothyrodism. I feel like things are stacked against me. Everyone seems to be getting pregnant, but me. I know it hasn’t been a year yet, but it’s hard when I have friends and family that conceive in less than 3 months or isn’t even trying and are pregnant. Any advice would be appreciated!
