back pain nausea abdominal pain

Is it normal to feel dizziness, weakness, nausea, abdominal pain, back pain when im 6wks?
this is my first ever been pregnant and feels like it's going to be the last, I feel weak, with a lot of nausea, fatigue, sleep, omg this is killing me …. thanx ..
If this is completely normal, ive had this before. just try and rest a lot, drink lots of water, eat healthy. We hope you feel better soon x
