45 days left... symptoms?

Hey guys I'm 34 weeks. I've been feeling pretty tired lately but also my nausea is back. I've been having yellow discharge and my boobs are becoming super sore like the beginning of my pregnancy. I've also started getting headaches and feet swelling even though I have them up all day. Does this all sound normal? I just feel like crap and my back HURTS. I'm a first time mom so not sure if any of these things are cause for concern.
