35 weeks pregnant and feeling nauseous and achy?

Its pretty normal to start feeling shitty towards the end of pregnancy. It could also be that you are getting a cold or virus and that is contributing to how you feel. If the cramping is not accompanied by a high fever or bleeding then it's most likely just normal and your body is getting tired and ready to give birth. There is a lot of shifting that goes on in the last few weeks as the baby might change positions and move down in your pelvis so that he or she is in the birth position. If you start feeling really bad you can call your OB and have them make sure its all just normal but it sounds like it to me.
