27 Day Cycle Overview
Ovulation: Day 13
High Fertility: Day 8 – 14 | Next Period: Day 28
When to Test for Pregnancy
Implantation typically happens 6-12 days past ovulation. If you have a 27-day cycle, testing before Day 26 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 28 (the day of your missed period).
