I had scans at epu at 6, 7, 8, 10 and 11 weeks. The first scan I had was both abdominal and trans-vaginal. For the abdominal bit I needed a full bladder. Once they had done the scan I had to empty my bladder for the internal scan. In the abdominal scan I saw the gestational sac and a blob in it. On the internal scan I could a flicker of a heartbeat in the blob. I didn't need to have any blood tests. Good luck, hope it goes well.
If it's an early scan they will most probably ask you to empty your bladder and it will be a trans vaginal scan. At six weeks you will probably be able to see something and they should be able to see something but it is a bit early so they may ask you back for another scan in a couple of weeks when there's more chance of a heartbeat etc.
most places will try the least invasive type of scan first so go with a full bladder expecting an external scan.(1L of water an hour before hand). If they can't see beanie then they will ask if you are happy to have an internal scan, to empty your bladder and they get a chaperone. It is mildly uncomfortable but not really anything to worry about. They slip a condom with lots of lube on it over the probe and are very gentle. You are given a sheet to drap over your legs and the mw keeps her eyes pretty much on the screen. You may be asked to give a blood sample to monitor your hcg levels. GL the early days of pregnancy can be so worrying.
Thank you both for responding, I'll go prepared with full bladder and then offload it if I need to (and I'll do full leg and bikini line just incase-I know they are use to seeing it, but its a bit wild there at the mo . I hope they will see a heartbeat, but I know its early and it might not be visible just yet.
