Well I ve been popping quite often the past 2 days, it s green. And lately my chest has been really tight and when I work out it almost feels really hard to breathe and I get dizzy and feel like I ll black out. I eat breakfast and all my meals every day. I ve been feeling sick when I run for cross country. I ve been in it for a while now so...I m not sure if its a sign I might start my period or what. I m breaking out like I usually do and I m very emotional. I haven t gotten it yet though and it s worrying me...
