Your urine is usually more concentrated when you first wake up. However, you can still take a pregnancy test at a different time of day. These tests assume a day luteal phase , which is the time between ovulation and when you get your period. The problem is that you may have a shorter or longer luteal phase.
If your luteal phase is usually 12 days, four days before your missed period would be nine days after ovulation. For you, taking the test four days before your missed period would be pointless. If you have a luteal phase of 15 days, four days before your missed period is 12 days after ovulation.
You still may not have enough hormones that early. However, you have a better chance than someone with a shorter luteal phase. An early test may detect the remains of fertility medication. Since the amount of hCG increases rapidly when you are pregnant, you may need to retest in a few days. If you are tempted to take a test before your period is late, consider the pros and cons before you do. Although, in theory, you could start taking pregnancy tests 10 days after conception, taking the test early may give you a negative result, even if you are pregnant.
As pregnancy hormones increase rapidly, the longer you wait, the more chance of an accurate result. The best time to take a pregnancy test is the day after your expected period, in the morning hours, with your first urination of the day.
