It's not about how far along you are really. The weeks indicator goes by approximately how much hCG is your wee at the time of the test. 1-2 weeks is 25-200mIU hCG, 2-3 weeks is 200-2,000mIU, and 3+ is 2,000+mIU. Not everyone hits those ranges at the same time and your hCG level in your urine can vary drastically from that in your blood based on numerous things. I've done those digis and gotten 1-2 weeks with a blood hCG level of 226 and 333. All it's telling you is that your urine has an hCG level somewhere between 200 and 2,000 mIU.
