I’m 16 and I was supposed to get my period at the end of October and it never came but around that time I was having a light brown discharge mix with a little bit of blood so I’m guessing that was my period but it was just weird because every time before I get my period my boobs are really sore and I have really bad cramps and I did not have any of that. The discharge stopped after a week and then I started having a sharp pain in my chest and feeling nausea and cramps so I took a pregnancy test and it came out negative. I haven’t had sex since the beginning of September and I got my last period at the end of September so idk I’m so confused
