I had this happen to me on 3 x sticks. I then went out and purchased a clear blue, and it was very dark 😅 to confirm what I thought I could see on the 3 ones before.
Some tests need stronger hcg to see a positive. Wait 48 hours and retest. Hcg doubles every 48 hours so you will see something if it is a positive
I thought you'd need to wait until after your period is due for high enough hcg levels to show up? I know there's more sensitive tests out there, but I'd say wait a couple days before testing again (if you don't want to wait until after you're due on).
You are pregnant. False positives are extremely rare. I took the test two days before my missed period. I could barely see the line. She's 4 months now. Didn't even bother taking another test.
Wait till you are late a least a week and then take the test with the first pee in the morning.
Any line indicates positive. Act as if you are pregnant (don't smoke, drink, no drugs) and test again tomorrow morning with your first pee. Then, let us know what happens. 🙂
