is it necessary to get pregnant only during ovulation?

No, you can get pregnant any time during your cycle. You're less likely around your period, but it can still happen. Male sperm usually lasts longer, so if you're no ovulating, you're more likely to get pregnant with a boy. Female sperm is faster, so you're more likely to have a girl when you're ovulating.
