I’m 18 years old and have been experiencing some discomfort around my left breast and back on the left side for a few days. I was supposed to have my period a week ago but my cycle is still super irregular. (I’m definitely not pregnant) Because of quarantine I’m afraid to go to the doctor unless it’s super serious. Should I be concerned about this pain? I don’t think I have any other symptoms and breast cancer doesn’t run in my family. I know this isn’t a medical source of info but I don’t really know what to do.
