Discuss OronD's answer to: I had unprotected sex 4 days before my ovulation date but my boyfriend came outside, could i be pregnant?

Unprotected sex at ANY time (yes ANY !) can result in a pregnancy.  True there are days with higher chances and days with lower chances but at ANY given day there are chances to get pregnant.  4 days before your ovulation is time with relatively high chances to get pregnant.  "Comming outside" is not a safe way to protect yourself..... in fact it is very unreliable way !.  Please note that even a "pre-come" can result in a preganancy.   TO make a long story short:  If you want to avoid being pregnant make sure you are always well protected !.
