How long should it take to get pregnant?

Around 85% of couples conceive within 12 months of regular unprotected sex. Evaluation is advised at 12 months, or 6 months if you are 35 or older.

Reviewed by Lunara Expert Advisory Panel · May 2026

In any given cycle, a healthy couple in their late twenties has roughly a 20–25% chance of conceiving. That compounds: most conceive within six months, around 85% within a year.

Standard guidance is to seek evaluation after 12 months of trying if you are under 35, after 6 months if you are 35 or older, and sooner if there are known factors such as irregular cycles, endometriosis, prior pelvic surgery, or a known male-factor issue.

Evaluation is not a last resort. It is usually a semen analysis, blood work, and imaging — information that often shortens the road rather than lengthening it.

The short version

  • Roughly 85% conceive within 12 months.
  • Seek evaluation at 12 months, or 6 months if 35+.
  • Semen analysis is part of the first-line workup, not an afterthought.

When to talk to a clinician

  • 12 months of trying under 35, or 6 months at 35 or older.
  • Known irregular cycles, endometriosis, PCOS, or prior pelvic surgery — sooner.
  • Two or more pregnancy losses.
