I don’t know what’s going on

I have been kind of your irregular with my period and I really hope that this is all about that because since Sunday I’ve felt a lot like a crying feeling. Today when I was taking a shower and one of the songs I have with my boyfriend was playing and I literally started crying like if I just had lost someone, like the crying was unstoppable and it got me pretty scary because I don’t know why I was crying that much like I was even sobbing.
