I'd be inclined to agree - a line is a line. I doubt you need encouragement but i'd test again in a few days, with first morning urine again, to see if the line is getting darker, then pop along to the doctor once AF is late.

If you're in the UK they probably won't do a bloodtest, just another urine one to make sure. And you probably won't get a dating can either, but you should get one at about 12 weeks to check everything looks good and to do the measurements for the abnormality tests if you want them.
