Nearly 6 wks pregnant symptoms

Lynn
Can anyone tell me if it is normal to have fairly consistent lower back pain and hip pain as early as almost 6 weeks? Haven't been yet to a doc. All pregnancy tests are positive. Doc appointment next week. Though now I'm a bit concerned as I've had this all week. First pregnancy, age 30, no heath issues at all, hardly even so much as a flu, naturally underweight bmi only about 16 but I eat well. Also been getting hot flashes.
