Hi everyone! So I'm 18 years old and my period is late eight days, and my breasts are tender. I'm still a virgin and the furthest my boyfriend and I have gotten is grinding against one another with four layers of clothes separating us. I've been very stressed for the past month and have gotten into walking more. I've also been experiencing a lot of new feelings I suppose too, but I'm still a virgin and have never done anything intimate with my boyfriend without four layers of clothes separating us. I'm really scared however as to why my period is late :( I took a pregnancy test and it was negative but I'm so confused as to why it is late :( Please help!!
