Q1: How accurate is this ovulation calculator?
A: This calculator provides an estimate based on average cycle patterns. Individual variations in cycle length and luteal phase can affect accuracy.
Q2: What if my cycle length varies?
A: If your cycles are irregular, this method may be less accurate. Consider tracking additional signs like basal body temperature or cervical mucus changes.

A: Common signs include mild abdominal pain (mittelschmerz), changes in cervical mucus, slight rise in basal body temperature, and increased libido.
Q5: When is the best time to conceive?
