I would wait to swim but it may not take a week. The more often you test and the more often you add bleach, the quicker the conversion will go. There is no such thing as testing and dosing with bleach too often. I can remember one person here on the forum a few years ago who completed his conversion in about 3 days because he tested and dosed every couple of hours. He was determined to get it done fast and he did!

Order that good kit ASAP. In the meantime, you can force the kit you buy in the meantime (that I listed above) to read higher by using a dilution method. Diluting is not super accurate but will be good enough in the meantime until the good kit arrives. Get some distilled water while you are at Walmart.

Testing Without a Good Kit

Did you see any of the pictures taken during a conversion process? Are you prepared for your pool to turn green? It can be a little scary to see it happen, but it will be worth it!
