Is it bad starting your period a week early, ? could you be pregnant.

Typically not: Having a early period does not typically mean you are pregnant. Sometimes it can be a result of hormonal changes, changes in diet or exercise, stress, thyroid, just a few reasons. If you're worried about becoming pregnant and you're not ready to be a parent, make sure to consider 2 forms of birth control as no one form is 100% effective. Even a pill is only 94-95% effective in prevent pregnancy.
