FAQ
Can I get pregnant with irregular periods?
Yes, pregnancy can still be possible with irregular periods, but timing is harder to estimate and some cycles may not include ovulation. A calculator can help with planning, but ovulation predictor kits, symptom tracking, and medical guidance may be more useful when cycles vary a lot.
How reliable are online ovulation calculators?
They are most useful when your cycles are fairly regular and your inputs are consistent. Online calculators rely on averages, so stress, illness, travel, postpartum changes, medication, or cycle conditions can shift ovulation earlier or later than the estimate.
Can I get pregnant right after my period?
Yes, especially if you have a short cycle (e.g., 21 days). Sperm can survive for 5 days inside the body, so early ovulation can overlap with post-period intercourse.
What is the "Fertile Window"?
This is the 6-day period each month when pregnancy is possible. It includes the 5 days before ovulation and the day of ovulation itself.
