I've got my 12 week scan tomorrow, although I'll be nearly 14 weeks. The appointment is at 9am, DH works near the hospital but has to be in work by quarter to eleven. I didn't think this would be an issue but I've just checked the letter and it says at times there can be a 3-4 hour delay in the department. Has anyone experienced this? We're going to get there at 8:30 when the unit opens, but if the scan isn't until 3-4 hours after my appointment time DH won't be able to stay, we work for the same government department and haven't told them yet and he really can't get out of his 11o'clock session.
