How likely is pregnancy on day 22 of cycle? i had unprotected sex on day 22, but he never came inside of me.

It depends : Since normal cycles can vary in length from 21 days to 35-42 days depending on your source and ovulation usually occurs 14 days before the onset of your period , the length of your cycle and thus when you ovulate determines how great the risk is but there is definitely a risk. If you aren't ready for a baby, now is the time to think about starting a reliable method of contraception.Hope this helps
