This is my second cycle that I have gotten a false positive on the first response. I did not order them offline, I bought them at Walgreens, Walmart, and CVS. They got darker as the days went by and I was 5 days late last cycle but went to the doctor with the test and they retested me. My urine came back negative and so did my blood. As expensive as these test are, they should be in working condition. I have the batch number also in the picture for the recent test box. Has anyone else had this problem lately?
