14 & 15 DPO tests

Are these tests too light for this DPO?? There is a little progression on the premom tests but the first response not so much (although they are different tests) Seeing how dark some people's lines are earlier is making me worry that this might result in a chemical. I emailed my doctor for an appointment so will hopefully hear back tomorrow to schedule a blood test. 🤞🤞🤞
