Well, I get kicks in the same place every single time. Nice hard ones that people can feel from the outside. Right above my pubic bone, on the right side of my pelvis.
This is TMO, but particularly when I have an orgasm, the baby seems to clench up because of the uterine contractions during the orgasm. I can feel the baby lump. What I percieve to be the butt and the head. The butt is on my lower left, and the head is slightly above and to the left of it, maybe about even with my bellybutton but way over on the left.
My midwife palpates my uterus to feel baby parts and see how baby is laying when I am at appointments, so she has helped me feel the baby parts too.
Usually much later in pregnancy, I can tell you how baby is laying. My last two have gone head down early in third tri and havent moved, with the feet up between my ribs, the knees on my middle right, the butt way over on the right, and the head engaged in the pelvis, sort of in a Z-type arrangement. Grace would even stick her foot way out on my right side and I could put my fingers around the length of her foot when she did it.
It is very uncomfortable when the baby decides to go transverse, since it is pushing out on the right and the left. Your uterus looks more like an egg standing on end then a circle, so when baby is transverse, he is pushing those sides of the egg way out.
