I took a test 2 days ago and saw a vvfl. It was suggested I take another one a day or 2 later so I took another one this morning. My vvfl is still a vvfl. Can this just be a bad test batch? It isn't expired. I also took a first response 2 days ago and that barely (you have to look really hard) registered anything. The first two pictures below are from 2 days ago and the last picture is from this morning. What do you ladies think? Any suggestions?
