If you are 16 years: Old and elect to be sexually active - you need to be more responsible. If you miss your period would take a home pregnancy test. It is imperative that protection is used every time if you are not ready for pregnancy.

Worries about?: One can worry about the relationship or about std infections, but if one has a period, that means not having to worry about being pregnant (during that time). Of course, one might get pregnant the next time she has sex. Having a normal regular period means a woman is not pregnant at that time. The usual time to conceive is about 2 weeks after the start of the last period.
