When I found out I was pregnant, I went to the doctor with my chart and told him that I'd had 3 +HPT's. He just said congratulations and wasn't going to do a test because he said the home ones are just as accurate as the ones at the GP and he looked at my chart and could tell from that as well, but we asked him to do a test just to make sure.

If you don't know when your LMP was, then you'll probably be booked in for a dating scan.
