Okay I just wanted to post a quick update. I waited two days and took the second test in the pack, and it now says 3+ weeks, so I feel much better! How it can go from 1-2 weeks to 3+ in two days beats me, but clearly it's not as reliable as they say. It caused me a lot of panic for no reason. I did see on another post that if your 6 weeks or more past ovulation, the test can give unpredictable results, but I don't know how true that is. I have my doctor appointment in two weeks So we'll know for sure how everything is going, but I will never use these tests again!
