Hi mama! This is normal. Your body is releasing hormones and relaxin to loosen the joints and ligaments in the body (and the pelvis!!) to prepare and make way for baby :) as a result, aches are normal. Sway from side to side and do wide walks (like an elephant) to open up the pelvis. You can bounce on a gym ball or do hip rotations which will help with the aches too. Sit on soft surfaces, it’ll be more comfortable
