4 weeks…

According to my lmp, I’m 4 weeks today. Is it normal to be getting small mild waves of nausea already? I haven’t thrown up or felt like I was about to. However, I’ve definitely gotten two small waves of nausea this morning. I’m not sure if it’s because I woke up super hungry or not. Also, is it normal to have cramping and some aches/pains this early? It’s not severe or hurting I just can feel them. No bleeding either
