Generally this happens around 12 weeks of pregnancy. Your healthcare practitioner can feel the top of your uterus by pressing on your belly. I wouldn't try this at home yet, it's still pretty hard to feel.
At 14 weeks pregnant the baby is still positioned mostly behind the pelvic bone. The growth of a uterus at 14 weeks gestation is about a inch above the top of the pelvic bone.
It is in the pelvic region roughly in the area of the pubic bone.

It doesn't. You should see a doctor...
The same place as a mans, above the legs and below the abdomen.
The uterus sits within the pelvic cradle, so it is protected by the three paired fused bones of the pelvis (the ilium, the ischium and the pubis) as well as by the sacral vertebrae that are also fused into the pelvis.
If you were into the second trimester, the doctor would be able to feel your uterus as it grew up past the pelvic bone at 12 weeks, 1 cm higher every week. After the miscarriage your uterus would shrink back to your pre-pregnant size below the pelvic bone, this is the only thing he would know by pressing on your tummy.
At 13 weeks your uterus can be felt right above the pelvic bone, at 20 weeks your uterus can be felt at your belly button. A multiple pregnancy (twins, etc) will cause more rapid growth of the uterus.
The penis is a soft tissue structure and is not part of the pelvic bone.
pelvic bone
The shape of the pelvic bones and the frontal bones differ.
No, it is the large bone in the upper part of the leg above the knee
