Finally got my wish but now getting nervous........

I haven’t had a good healthy pregnancy in 6years and I’m now expecting my rainbow baby in I’m happy for the most part but I haven’t always been happy about this pregnancy due to being sick and being on medications in having to leave my job due to sickness I had hope this baby would have been my little girl I been praying for in wanting but of course I end up having another boy my 3rd boy was hurt and very sad but then I prayed I would have my son on my birthday so we could be birthday twins and I finally got it but now my nerves are kicking in because I’m starting to realize that I won’t have two kids no more in that I’m actually about to have a little baby in our home a baby that I’m not babysitting in will be waiting for the mom to pick the baby up but my own baby and my other boys ages 8-6 doesn’t know what to expect because it’s always been us and the funny thing about this is my oldest turned 8 this year and my youngest turned 6 this year in my birthday is 8/6 in I will be having my son 8/6 so I felt like it was only right to have him on my birthday because my birthday came in 3s this year I pray I have a safe surgery and I pray everything comes back natural for me since I haven’t done this in sooo long it just feels so wired for me
