I am 6 weeks 3 days and i am having cramps in my stomach and lower back pains is this normal?

Maybe.: If you are having such symptoms at 6 weeks, you may be experiencing the furst stages of a miscarriage, or you may be hurting from the growing uterus that stretching its ligaments as the live embryo is getting it larger. If your symptoms worsen, i would recommend seeing your gynecologist to assure fetal viability. Take Folic Acid 1-5 mg daily orally! best of luck!
