Sensitivity?

Sarah❤️
Are the old style frer test more sensitive than the new ones? I took an old style test last night and it had a faint line. The test I took today was the curved style, and I think it has a vvvvfl, but not enough to convince me it's there. Im so confused. :( top is last night. Bottom is today tweaked and yes it has color in person. Just can't get a good enough pic because the line is so faint. HELP!!
