Ttc but bridesmaid in the summer

I have been ttc for 8 months now. I had a miscarriage earlier at the beginning of the month too. Originally when I was asked to be in my brothers wedding I was 9 weeks pregnant and lost the baby. Today my mom made the comment that I should stop trying to conceive because my bridesmaid dress isn't going to fit and I need to put the baby trying all on hold. The wedding in in July. That made me so mad! Does anyone else think like me?
