What is the likelihood of getting pregnant if had sex on cd 17 of a 31-33 day cycle but he did not ejaculate in me, and ejaculated much later than being in me, was not inside not even before he ejaculated and ejaculated obviously outside?

Pre-cum can contain enough sperm to cause pregnancy. If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. If you do not wish to be pregnant, use contraception all the time, every time. Wish you good health!
