When to Take Pregnancy Test Calculator
A pregnancy test calculator helps determine the optimal time to take a pregnancy test based on your last menstrual period (LMP) and cycle length. It calculates when the pregnancy hormone (hCG) becomes detectable in urine, typically 1-2 weeks after conception. This tool minimizes false negatives by suggesting testing dates after a missed period, considering ovulation patterns and implantation time. Accurate results depend on regular menstrual cycles and proper date input.

Calculation Formula
Optimal Test Date = LMP Date + Cycle Length + 7-14 days
1. Calculate expected period date: LMP Date + Cycle Length
2. Add 7-14 days after missed period for accurate testing
3. For irregular cycles, add 21-28 days from conception date
