Welcome Flambola, and so sorry to hear of the loss of your bonny son and on Christmas day of all days.
I lost my little girl nearly a year ago, it's her birthday on Tuesday. The pain does fade with time, but it takes a good few months to feel anywhere near normal again so be kind to yourself.
I was advised to wait for 9 months before TTC again for medical reasons, and the wait was torture at times as I had that same deep need to be pregnant again (which faded after 4-5 months I would say). I'm now 6-7 weeks pregnant, and definitely more anxious this time round, but still totally delighted to be pg and very relieved that it didn't take forever after starting to try. The ladies on this thread are all so strong, life goes on and we all manage somehow, but it's great to have such a lovely group to rant to and answer questions and hear stories.
In terms of care, every NHS trust seems to be different, so you will have to ask some questions to figure out how it works in your area. As Ducky's story shows, sometimes you have to stand up for yourself and make a bit of a fuss. First thing for you will be to make sure you get your 6 week post-birth appt, with your consultant obstetrician, not your GP. You can ask them about what to expect for your next pregnancy. My hospital has a specialist bereavement midwife as well.
I also got some extra tests done (blood test, GUM check, and a cervix/vagina scan) to check everything looked normal before I started TTC again. But I had to push to get that. And they didn't find anything.
Vicky, I have actually told my best friend, partly because she's working abroad at the moment so we email a lot, and it almost felt like an extension of MN to email her. I had to swear her to secrecy as her mum is friends with my mum! We're trying to keep it quiet for as long as possible in general though, and I don't think I'll be doing a FB announcement at 13 weeks or anything like that. I will just tell people as I see them and feel it is the right time.
We've got some friends/family who I know are having fertility issues, and others who we suspect might do. Going through a loss just makes us a bit more sensitive to that. I don't want to celebrate being pg (only having a safely delivered baby), and I equally don't want to rub it in anyone's face.
Sorry to hear that neither of your parents coped well – I am on the same page as you totally that you can't use this as a reason not to get on with life. Both sets of parents were pretty good with us (actually I've just received a lovely card from my parents for 'G's birthday), but I wouldn't/couldn't open up to them and talk in the same way I could with my girl friends. I think it's because you know parents feel pain too, and feel like your story could cause them more pain – their pain is partly for you but partly for themselves too. With friends, their sorrow is all for you.
