My 3rd pregnancy!!!

So i found out i was pregnant on 12/10/2015 so if I'm calculating correctly I'm 5 weeks and 3 days!!! This pregnancy was unexpected. I already have 2 girls my oldest is 3 about to be 4 in January and my youngest 1 going to be 2 in march!!! So me and my husband weren't trying for another baby but it happened. And so we are going to roll with the punches!!! I'm kind of sad and disappointed because my sister in law is pregnant going on 5 months so i feel so bad because the spot light should only be on her :/ So me and my husband decided to keep it a secret until we are ready to let everyone know. I know we might get judged because we already have 2 little one's. Just thought i should vent because know one else knows how i really feel.
