Does my hair fade and menstruation late?

Discolor the hairs on my body from the arms, legs, back and belly I used bleach and water oxygen vol.40 last week, only that has a week that my period has not yet come, if I get pregnant will it be that it can do harm to my baby . I never got pregnant and now I'm very scared of being pregnant and have some problem ... Help me please this already happened to someone and something happened ...
