Would you postpone TCC?

Would you put off TTC for a family member's upcoming wedding? The backstory: we've been TTC for almost a year, I'm 31. In October I got our first BFP but unfortunately that ended in a miscarriage around 6/7 weeks. We spent some time grieving and waiting for my period and now my husband and I want to try more then ever, especially after losing my first pregnancy. My husband's sister is getting married out of state next September, and we are both in the wedding party. Is it selfish to continue tcc right now or would you wait a couple cycles? I would feel horrible if we missed their wedding but I also feel like we need to continue living our life and timing a baby isn't as simple as it seems...
