Congratulations on the birth of your beautiful baby boy. I am so sorry that he couldn't be with you for longer than he was...
It will take time for your body to get back to normal... Once you have stopped bleeding, which could be up to 3 / 4 weeks (but could be less) it is just a case of waiting for your period to return. It is only breastfeeding that suppresses the reproductive hormone that brings on periods, your cycle could return within a few months, but may well be irregular. You can start to TTC as soon as you feel ready too, but it is best to wait for your first monthly period at least so that you have a good idea of your dates.
Good luck for the post mortem results. I hope it's the best news it can be, that it was a random birth defect and not a genetic problem, so that you can try again with minimal stress of this occurring again...
I am so sorry for your loss. May your little angel be happy where he's resting now.
I thought of you and closed my eyes, and prayed to God today; I asked what makes a mother and I know I heard him say....
God: A mother has a baby, this we know is true.
Me: But God, can you be a mother, when your baby's not with you?
God: Yes you can.
(He replied with confidence in his voice)
God: I give many women babies - when they leave is not their choice. Some I send for a lifetime, and others for a day, And some I send to feel your womb but there's no need to stay.
Me: I just don't understand this, God. I want my baby here.
(He took a breath and cleared his throat, and then, I saw a tear.)
God:I wish I could show you what your child is doing today. If you could see your child smile with other children and say,
"We go to earth to learn our lessons of love and life and fear. My mummy loved me oh so much, I got to come straight here... I feel so lucky to have a mum, who had so much love for me; I learned my lessons very quickly - my mummy set me free. I miss my mummy oh so much, but I visit her each day. When she goes to sleep, on her pillow is where I lay. I stroke her hair and kiss her cheek, and whisper in her ear, 'Mummy, don't be sad today, I'm your baby and I'm here.'"
God: So, you see, my dear sweet one, your child is okay - your baby is here in my home and this is where he'll stay. He'll wait for you with me, until your lesson is through - And on that day that you come home, he'll be at the gates for you.
So, now you see what makes a mother; it's the feeling in your heart. It's the love you had so much of, right from the very start.
