OMG! I have been a long time away from this site, so I did not know that you lost your son! I cannot imagine what you are going through but I thank God for this amazing gift he's giving you now! God indeed work in mysterious ways! As a woman who is struggling to have a baby myself, I do understand the anxiety you're going through now, and I do understand that you want to wait 3 months until you announce the news!
I want to tell you that even though I don't know you personally, I want you to know that I will be praying for you, I hope that your pregnancy goes well and that your new baby will bring along all the joy into your world and will keep you strong and rest assured that the son you lost is an angel watching over you from above.
I really have tears in my eyes now since it hasn't been long since I "lost" the baby I never had! I mean it was just an embryo, but still I felt that it was my baby, so I cannot even start to imagine what you went through! But see... God is making it up for you now

All my prayers are with you
