kayleigh hello, so sorry that you are here and lost your precious little boy. I love the name Ben, it's always been one of my favourite boy's names. Good luck with TTC, it's great that your doctor has given you the green light, although I know it will be an extra stressful time for you. I lost my little son James in January and am just now pregnant with his brother or sister - it's super early and I am worrying but from reading about the other ladies on this thread, I reckon that is going to be par for the course.
earth I love reading your posts and don't want you to go. It's so nice to hear from someone who has been through the stress of a rainbow pregnancy and survived - all the emotions and fear that go along with that.
missalex A boy, how lovely. It's hard with the gender thing because basically we all just want our lost babies back (although we also fiercely love and are terrified about the safety of our rainbow babies) and I'm sure it underscores that this is a different baby to your son. I have a gender preference for a boy with this pregnancy (although what I want most is just a healthy baby - please, God) and I know I will have complicated feelings about a little girl, just because of James. What I really want is him and I can't have him. My mum went on to have two girls after losing her son and she said she's always felt a little wistful about not having another boy, even though she adores me and my sister and wouldn't swap us. It's so complicated isn't it.
I won't be seeing the midwives again - just our wonderful obstetrician. I'm in the US where obstetricians are more normal, but I had specifically chosen midwife care with my first pregnancy because I wanted a natural birth . The (very young) midwife on call the night James was born didn't tell us to come in straight away when I told her I had had heavy bleeding. I know she feels guilty about it. It meant we delayed by about an hour. The doctors have told us it probably wouldn't have made any difference, but I will always have that 'what if'. And the chief midwife, whose caseload I was on, took three days to come and see me, got our baby's name wrong, and clearly hadn't had a conversation with the obstetrician about what exactly happened. So I just don't trust them.
blue hope you're doing ok and managing the anxiety. I can imagine it'd be incredibly stressful, the stage you are at. I am looking forward to feeling my baby move but also will be terrified because of the sense of responsibility.
atm how are you feeling? Any MS yet?
betty thinking of you and hope you're managing ok. 
august how lovely of you to post, so sorry you lost your little boy, and glad that you've survived and had another little son, although it doesn't make up for what you went through.
ducky the period in between 12 weeks and 20 weeks must be dragging I am sure.
ruby did you have your 28 week appointment yet? What sort of monitoring are they giving you - non stress tests? scans?
Hope everyone else that I've met on this thread is doing ok.
