Evidence-led conception guide
How to get pregnant without turning timing into a full-time job
There is no trick that guarantees pregnancy. A useful plan combines a realistic view of the fertile window, preconception health, regular attempts, and a clear point for asking for fertility help.

Understand the fertile window
Sperm can remain functional for several days, while an egg is usually available for fertilization for about a day. The fertile window is roughly the five days before ovulation through about one day afterward, with the highest chance near ovulation.
Ovulation often occurs about 14 days before the next period—not automatically on cycle day 14. Calendar apps estimate; they do not confirm ovulation.
Choose a timing plan you can actually live with
For people using intercourse to conceive, sex every day or every other day during the fertile days is a common evidence-based approach. If tracking increases distress, sex every two to three days across the cycle can cover much of the possible window.
Urine ovulation tests detect a rise in luteinizing hormone about a day before expected ovulation. They do not prove that ovulation occurred, measure overall fertility, or guarantee conception.
- Follow the test directions and note the time of day.
- Use tracking as optional information, not a scorecard.
- Special positions, lying still afterward, fertility teas, detoxes, and supplements with guarantees do not create a guaranteed pathway.
Prepare health before and during attempts
Review health conditions, vaccines, prescriptions, over-the-counter medicines, supplements, alcohol, smoking, cannabis, and other substances with a healthcare professional. Do not stop an important medicine on your own.
CDC recommends 400 micrograms of folic acid every day for people who can become pregnant, starting at least one month before conception. Some medical situations need different guidance, so ask rather than increasing the dose yourself.
Include every path to pregnancy
Donor sperm, insemination, IVF, reciprocal IVF, donor eggs or embryos, surrogacy, and fertility preservation can be part of conception planning. The right first contact may be an ob-gyn, primary-care clinician, reproductive endocrinologist, urologist, fertility clinic, or LGBTQ+-competent family-building service.
Ask about total costs, success rates for people with similar circumstances, medication and monitoring, legal needs, donor screening, and emotional support before committing.
Know when to test and when to ask for help
A home test is reasonable from the first day of a missed period, but an early negative can be wrong. Repeat after several days when pregnancy is still possible.
Seek fertility evaluation after 12 months of regular attempts if the person who would carry the pregnancy is under 35, after 6 months at age 35 or older, and before waiting if over 40. Ask sooner for absent or irregular periods, severe pelvic pain, known reproductive conditions, prior chemotherapy, sexual or ejaculatory problems, or more than one miscarriage.
