I'll try to keep this as brief as possible but really feeling like I need some support and advice at the moment and not sure where to turn...
3 years ago (almost to the day) we made the heartbreaking decision to have a termination at 23+ weeks due to a very serious brain abnormality that was detected on the 20 week scan. I still actually can't quite believe that it all happened - it's almost like I look back on that time and it wasn't me.
DH has been fantastic and one of the things that got me through at that time was looking at our fantastic children and looking towards our future with them.
Fast forward 6 months and we had a good long chat and decided that we wanted to try again. Even though I will always be sad about our baby boy and this would never take that away, I was so excited about the prospect of a child with DH. (Our dc are from previous relationships on both sides.) Tried for the best part of a year and nothing happened 
Then life got a bit crazy! Redundancy threat at work, my youngest and my step-son were both poorly, and life was hectic. So we decided to stop trying 'for now' and just focus on work, life and the children.
Which brings me to now. We are now 3 years down the line and I have not long turned 41. Our youngest (who is my step son) is 9, and we are both working hard and have some potentially fantastic career opportunities coming up over the next couple of years. Plus I'm not getting any younger.
Logic is telling me that I need to now put this all behind me, accept that we won't ever have a baby between us, and focus on what we do have, making the most of life, and looking forward.
But my heart is telling me I still want to try one more time. In fact I keep actually bursting into tears when I think about it all.
(I wasn't even this bad at the time everything happened!)
Don't know what I'm looking for here really other than to get it all out. Maybe advice on where I may be able to get some support or counselling from someone who understands?
Or some advice on how to choose between head and heart?
Thanks if you got this far!
