Thats great news ChloeNat, so good that you can relax now.
Im a bit unsure about my due date too, going by the date of my last period Im due 2 May, but at the early scan I had they put me at 30 April. Im going to wait for the 12 week scan to confirm it but either way I think Ill stay in the May mummies thread as Ive heard its quite normal to go a little over with your first, and Id like to keep up to date with you all.
