I'm 17 and I started my period when I was in 3rd grade so around 8 years old because I had a growth spurt. My period is late but I am still a virgin. The only thing I've done with my boyfriend is dry humping and he never ejaculated either. So I don't think pregnancy is possible. Is there a reason why my period is late? I've been having symptoms like acne, sore breasts, eating a lot but no period. According to my period tracker, my period was suppose to come yesterday but it never came and it still hasn't come today.
