Likewise, your ovulation time frame might be a bit longer than other people, so you can't accurately guess when it's 'safe' to have sex.
It's always best to use birth control and condoms - keeping you AND your partner safe from possible infections and pregnancy.
Ovulation is also a tricky thing - just because it usually happens mid-cycle for most women doesn't mean it's automatically Day 14 you should be worried about. Ovulation is different for everyone.
Women who are TRYING to get pregnant often spend months and months trying to figure out their pattern of ovulation - through daily temperature taking, feeling their cervix, checking their discharge - so as you can see, it's a complicated thing.
