I'm starting to worry that something may be wrong with me. My period last month came five day late (since the 14th is when I start), and this month since I started on the 19th I am techniqually two days late, but 7 days late if I do it by the 14th on when it actually is supposed to start. I've been having diarrhea that not normal (it's literally dark green), and my period this month is shorter than usual. I am not experiencing my bad cramps that I normally get, and instead I feel nauseated all the time. I've been really emotional more than usual. During my period I can control my emotions, and now it just seems I'm having weird mood swings and I cant control them. I'm not thinking I'm pregnant because I have PCOS and am infertile' however, my ovaries are doing a lot better and I have a higher chance at getting pregnant now. I've read about everyones symptoms matching mine, and it leads to pregnancy. Could I be pregnant? or could it be something else?
