if it's not in your tube it's perfectly ok. your body IS stretching and pulling to accommodate for bump
No it's not my tubes......its sort of where my leg & pelvic bone meet...probably stretching which is what i thought at first but just wanted to be sure!
It doesn't sound like 'round ligament pain' which is caused by the ligaments which hold the uterus stretching and kind of snapping like elastics being pulled/snapped BUT your body is producing a lot of hormones such as relaxin causing muscles and joints to relax and spread. This is probably what you are feeling and it is just giving you an ache because they are moving and extra loose.
Either way, it is okay and normal =)
