For best results, the best time to test Is sometime In the morning after you miss your period due to the HCG hormone, but there are some tests out there that you can test earlier with accurate results, It really depends on the type of test. Depending on the amount of HCG In the urine at the time you take the test, the color of the line will vary In Intensity. So If you do It too early when there Is not enough HCG, It can cause a false negative. I personally took Clear Blue Digital when I was 6 days late, and another at 7 days late.
I took a furst response early one and found out like 3-4 days before my period was due so wait til like the 22nd atleast and do the 6 days sooner first response if your inpatient like I was lol.
I also hadn't had my period yet, it was a week away. I obviously missed. Lol
I found out I was pregnant at about 2 weeks on a hpt. Went to the dr a week later and I was. The line was very faint though. But Im definitely pregnant. Lol but everyone is different. Good luck!
I would wait a week after the missed period this early they can only tell by drawing blood
