With a 29 to 32 day cycle, day 23 is past your usual fertile window, but ovulation timing can shift a little each month, so it isn't a guaranteed safe day.
Next Steps
If your period doesn't arrive as expected, take a home urine
pregnancy test about 3 weeks after that intercourse for a reliable result.
Health Tips
Testing too early can give a false negative, so try not to test before your missed period.
