I took a test 3 days early and got a faint line, then panicked thinking it was evaporation! But it turned out to be positive. Just wait a couple of days if you want a clear dark line.
Oh, the wait is the hardest part, right? I am also in the same boat and trying to control myself from testing early! Let's wait a few more days together.
I was so impatient that my MIL caught me hiding the test kits, haha! She told me to wait patiently for a few days because testing too early just causes unnecessary tension.
You can try with an early detection kit, but honestly, it can still show a false negative. Best is to wait till your missed period day to save yourself the stress.
Medically, the hCG hormone levels might not be high enough 3 days before your period. My doctor told me that testing on the day of your missed period gives 99% accuracy.
