How long does it take to get pregnant?
Bottom lineAbout 8 in 10 couples conceive within a year and around half the rest in the second year, with a roughly 15 to 25% chance per cycle under 35, so several months without success is normal; age, timing to the fertile window, cycle regularity, and health all matter. Seek help after 12 months if under 36, sooner (around 6 months) if 36 or older, and early if you have irregular periods, endometriosis, or PCOS/PMOS.
For most couples having regular, unprotected sex, conception takes time and is spread over months. It's normal not to conceive in the first few cycles.
The typical timeline
- About 8 in 10 couples conceive within 1 year
- Around half of the remaining conceive in the second year
- Most months, the chance of conceiving is roughly 15 to 25% per cycle for those under 35
So a few months without success is expected, not a sign of a problem.
What affects it
- Age: fertility declines gradually from about 32, more steeply after 37
- Timing: having sex in the fertile window (the days before ovulation) matters most
- Cycle regularity: irregular ovulation makes timing harder
- Health factors: weight, smoking, alcohol, and underlying conditions
When to seek help
- Under 36: after 12 months of trying
- 36 or older: sooner, at around 6 months or when you raise it
- Any age with known issues (irregular periods, endometriosis, PCOS/PMOS): get checked early
