A member asked:

What is the chance of a girl with a fairly regular period of 30-31 days with 33 as the longest getting pregnant with sex on the 28th day?

A doctor has provided 1 answer

?: If i understand your question - having intercourse on day 28 of a 30-31 day cycle is way too late. Typically ovulation is 14 days prior to the end of your cycle. Day 16 for a 30 day cycle. Day 17 for a 31 day etc.
