I had mine at 16+5 with ds4 and it was really obvious he was a boy at that point so I think just 2 days off of 16 weeks would be ok.
Now I know I probably sound mental. But I've reached the point where I feel like maybe it's all going to be ok (I know I know, I'll probably be back in a couple of weeks crying about needing a daughter) but after the recent GD dip which I feel like was the worst I've experienced yet, I just don't think I can do that to myself again. Of course I'm scared of the regret, but dh says that we can try again and sway in the future if I want to. I saw my mum the other day and we are not close at all. And it made me think, if I can be closer with my boys, then in 40 years will the little dresses and hair clips I didn't buy really matter that much?
I really think it is like grief, I've been sad, I've tried to convince myself it will happen one day, I've been so angry that i didn't get a girl when others have. I think I've reached acceptance. Like with the way I miss my nan still after 5 years, I think I'll always wish I'd had a girl. But I've looked at my life, and the things we'd have to change and give up for 1 more baby. And I feel it's selfish of me to just keep going for the chance of a girl. I feel I'm ready to move on to the next stage of parenting. I'm fed up living in the future, hoping but not daring to hope, planning the next pregnancy before I've even had the baby I was carrying.
I've been lucky to have 4 healthy boys.
I'll still be around to see how you all get on. Maybe not as often. And I may need to come back and vent if it gets tough. But I'm ready to move forwards with my boys and don't actually feel anything or anyone is missing.
