Whether you've just started trying or have been trying for several months, knowing when to have intercourse, how to identify ovulation, and when to take a pregnancy test can improve your chances of conception while reducing unnecessary stress.
Understanding Your Cycle
The menstrual cycle begins on the first day of full menstrual flow (Cycle Day 1). The first half of the cycle prepares an egg to mature. Ovulation is the release of a mature egg and occurs once during the cycle. The second half of the cycle is called the luteal phase, when the body prepares for implantation.
Menstrual Cycle Timeline
How to Track Your Cycle
- Mark the first day of every period
- Record cycle length each month
- Note cervical mucus changes
- Track ovulation predictor kit (OPK) results
- Record basal body temperature (if using)
- Log intercourse
- Record pregnancy tests
Identifying Ovulation
You do not always ovulate on Day 14. Ovulation usually occurs about 14 days before your next period, regardless of cycle length.
Ovulation Predictor Kits (LH Tests)
LH tests detect the hormone surge that occurs 24–36 hours before ovulation.
When Should I Start Testing?
Fertile Cervical Mucus
As ovulation approaches, cervical mucus changes.
Best Days to Have Intercourse
Sperm can survive up to 5 days inside the reproductive tract. The egg survives 12–24 hours after ovulation. Because of this, intercourse before ovulation is more important than after.
Recommended Timing
Tips
Have intercourse:
- Every 1–2 days beginning 5 days before expected ovulation
- The day of your positive LH test and the following 2 days
Implantation
After ovulation, fertilization usually occurs within 24 hours. Implantation most commonly occurs 6–10 days after ovulation. It is normal to have no symptoms during implantation.
When Should I Take a Pregnancy Test?
Testing too early can lead to false negatives.

Common Questions
We missed the day of ovulation. Is it too late?
Possibly. The egg survives only about 12–24 hours, so intercourse before ovulation gives the best chance.
Should we have intercourse every day?
Every other day throughout the fertile window is usually sufficient. Daily intercourse during the fertile window is also appropriate if it is comfortable and enjoyable for both partners.
My LH test never turns positive.
Some people have very short LH surges or do not ovulate every cycle. If this happens repeatedly, let your provider know.
I have irregular cycles.
Predicting ovulation can be more difficult with irregular cycles. Your provider can help determine the best strategy and whether additional evaluation is appropriate.
