Hello im 16 years of age and Ive been in a relationship for 9 months now, recently we have been getting close contact and have did stuff but not sex. I have missed my period recently for the second time and im getting a little worried. I know i shouldnt because i havnt had sex but is there any reason why my period might be late. My friend said it could be that because I have been constantly been doing stuff i hvnt gave my body a break to release an egg?
