I just want to complain! I've been having a hard time sleeping at night, been feeling nauseas the past two days, and throwing random moods at my poor husband. I don't mean to and don't even notice until he points it out.. I don't think I'm pregnant because I just had my period on the 13th and I haven't even ovulated yet. Is this something that happens close to your fertile window? I doubt it but you never know I guess..
