Oh Manda, it sounds like your head is all over the place. I wonder how you'll feel if you get a BFP or BFN, maybe that will tell you whether you really do want another dc?
You probably are protecting yourself somewhat, you've been through a terrible experience and are trying to stop it happening again in the only way you can.
I felt awful when I first discovered I was pg, I thought it was too soon and I wouldn't be able to cope with two little 'uns. When I mc it made me realise how much the baby was wanted and how much I'd give to be pg again. I knew I would regret not having or trying to have another but wouldn't regret having a baby. Do you think you'd regret it if you didn't have another? How about if you did?
Give yourself time to grieve properly and think with a clear head and I'm sure the right decision will emerge.
Poppyjen, I think you're a cycle buddy with me and Manda, we're both 4dpo. Given the stats, that would mean that one of us is likely to have a BFP this month! Oooh, good luck! Unlikely to be me so it's between you two... no pressure though 
My dd (23m) is currently crying in her cot, desperate for sleep but unable to settle. I think it's the heat so I feel your pain. It's frustrating, she's so overtired and really needs a good kip.
Whingey hope you're feeling more positive? I had a bad day yesterday. I had been feeling good for a while so was a bit taken aback to be down yesterday. I think it was because I met up with one of my friends who's due two weeks before I would have been and had an email from another friend announcing that she's 17 weeks pg. I was so jealous of them both and felt really upset. I also realised that I've got to wait nearly a month before we can try again and wish the time would speed up, it seems to go so slow.
MissG have you POAS recently?
