Bridesmaids at 8mo yikes!

Haidee • 30 yrs old- female
So 2 of my best friends are getting married this year. One on Oct 10th & the other Dec 11th, what are the chances right? I was super nervous the one of Oct 10th & was even willing to step down as Bridesmaids. Well she is super happy for me & definitely still wants me to be a bridesmaids, how excited & relieve I feel. Now the Dec 11th wedding, I think I could wait to tell her right? 
Anyone has been through this before? Or gotten married with a big belly?
