Hindi ka nag-iisa! A few of us sa barkada namin didn't feel much tenderness either, especially sa early weeks, iba-iba talaga ang pregnancy symptoms from person to person, so don't worry. Pero since you're 9 weeks na, mas safe pa rin na i-check with your OB just to make sure everything's progressing well, kahit walang breast pain, they can do an ultrasound to confirm lahat's good with baby. Some moms lang talaga get that symptom, some don't, but your doctor will give you peace of mind!
