While first morning urine is best to avoid false negatives, it is always safest to get a proper beta hCG blood test to confirm. If you are confused by faint lines on home kits, please consult your gynac. They will do a proper scan or blood test to tell you the exact status safely.
It is not absolutely necessary, but first morning urine gives the most accurate result because it is concentrated. If your period is already late by a week, you can test at any time of the day. Take care.
Honestly, I got so anxious when I tested in the afternoon and saw a faint line, and then I kept googling if I ruined the test! If you test with the first urine, the hormone is much stronger and it saves you from all that unnecessary worry and overthinking. Just try to wait until morning to do it, it's much safer for your peace of mind.
Using the first morning urine is mostly recommended because it has the highest concentration of hCG hormone, especially in the early days. When I was early pregnant, I tested first thing in the morning and then went for my light morning walk which my doctor had allowed. It's just a more reliable way to get a clear result.
Not strictly necessary, but highly recommended for a clear result! First morning urine has the maximum hCG hormone level, especially if you are testing early 😊. If your periods are delayed by many days, you can test anytime. All the best! 👍
My doctor told me that early in pregnancy, hCG levels are quite low, so concentrated first morning urine is ideal for home kits to detect it. If you drink a lot of water before testing during the day, the urine gets diluted and might show a false negative. If you're already past your missed period date by a week, any time of day works fine.
