Hi,
you should be able to get a scan- I did, at about 8 weeks. (i was unsure of my dates)
they should give you a referal if you tell them you are having some pains-even small ones- I was planning on getting one to confirm my dates anyway (which was recommended by my gp when I had all my blood tests and stuff early on, but hadn't got around to it yet, and then I had a few twinges one morning, so I figured, good a time as any, went in to a gp(not even the same one), and had the scan later the same day to make sure everything was all cool, and i'm in melbourne, so it should'nt be any harder for you.
No harm in asking anyway.
Hey- I was you three years ago!!! I found out 14th june that I was pregnant, and I was almost 8 weeks already, so I would have been about 10 weeks or so about now. My original due date was 9th feb 2003, but my daughter (sinead) came on 17th january instead-drama queen!!!
When's your due date?
