Okay so for the past 2 weeks I have had some crazy symptoms that lead me to think I might be pregnant. I have been so moody like I have never been this moody in my life I get upset or mad and I don't even know what it's over. I have terrible back pain like right above my butt. I get headaches like crazy. I'm constipated 24/7 and when I finally poop it's bright green. Also I can be starving and eat my husbands leftovers and all my food and the next day I don't want to eat anything and just the thought of any food makes me want to puke! I took a preganancy test last week but it was negative but I thought maybe it was too early to tell? I need help please!!
