I wondered the same when I took one today and got a positive within 2 seconds. Can only be almost 5 weeks. Calling OB tomorrow. I'm almost positive it's not a false positive.

Re: anyone use a walgreen digital test before?
Digitals are usually less sensitive then other tests like FRER. So if you are really early that is probably why.
Congrats on your pregnancy!
