Ladies, it sounds like you are describing "round Ligament Pain" which means the ligaments holding your uterus in place are stretching which causes a pulling sensation down in the groin/upper leg area thru into the pelvis. It is worse when you are active and settles down if you slow down. Take heart that it is all normal and just your body stretching to allow bubs to grow. Take it easy when you feel the pains. My best advice is LISTEN to your body. It knows what it is doing. Keep up the fluids and rest when you need to.... Goodluck girls, hope things settle down for you soon!
