Sort of, but not specifically for that reason. This will be our last month trying for about 6 months - if it works, we'll have an early October baby. If it doesn't, we'll be waiting until June to start trying again, which would be a March EDD.
We will be moving in April to Virginia for 6 months of training for my husband, which isn't a big deal, but we'll be moving again the end of October, and we don't know where yet (and won't know where until mid-August) so I don't want to be very pregnant and have to move to, say, Japan or Hawaii or Guam.
My birthday is right before Christmas and I've always hated it. I love my birthday, but I hate that I can't ever really do anything for it. Born right after the holidays is so much better than before. December birthdays aren't that great.
