Okay so basically my period always comes around the 10th however I went away on vacation, had symptoms the whole time but never got my period. This morning when I woke up I had horrible pains (as usual) so I thought there was no way I couldn't not have it. I still don't have it. I'm going to my boyfriends tomorrow and we're both against sexual activities (for myself) while I'm on my period. I don't know what to do because this feels not normal.
