28 Day Cycle Overview
Ovulation: Day 14
High Fertility: Day 9 – 15 | Next Period: Day 29
When to Test for Pregnancy
Implantation typically happens 6-12 days past ovulation. If you have a 28-day cycle, testing before Day 27 might yield a false negative because hCG hormone levels haven't concentrated enough in your urine. The most accurate time to test is on Day 29 (the day of your missed period).
