What does a 4 month old fetus kick feel like? is it like a thump coming from the inside?

I guess: A female dr who had children would be best to tell you, but my wife said that is a good description. You feel a "bump" coming from the growing baby, which may be a kick. Congratulations and best wishes.

More like gas: .I don't have any personal knowledge however from what the women tell me they report more of a tingling or rolling at four months. At the four-month. The fetuses just coming out of the pelvis and uterus are starting to enlarge significantly. I don't think you're going to have too much something until the infant grows some. By the time you're ready to deliver the child is kicking field goals.
