3 days late for my pierod and im cramping sore boobs white discharge nauseated bloated cramps

why 5 weeks after my pissed pierod I thought is was you can take one right after our six days before

Because u only start producing a detectable amount of pregnancy hormones around 5 weeks after

Accodording to the Office on Women's Health in the Office of the Assistant Secretary for Health at the U.S. Department of Health and Human Services, it's about a week after a missed period, although some HPTs claim to be effective on the first day of your missed period.

How soon after a missed period can I take a home pregnancy test and get an accurate result?

Many home pregnancy tests (HPTs) claim to be 99 percent accurate on the first day of your missed period. But research suggests that most HPTs do not always spot pregnancy that early. And when they do, the results are often so faint they are misunderstood. If you can wait one week after your missed period, most HPTs will give you an accurate answer. Ask your doctor for a more sensitive test if you need to know earlier.
