Should this start so early?

im 7 weeks pregnant with my second baby. on my first more toward the end i had severly sore hip pain if i sat to one side or if i slept on my side i would be woken in agony with my hip? walking etc also caused the pain but i am starting to feel it again quite strong and was just wondering should it happen so early in pregnancy when im not even showing so no pressure on hips?? thanks
