Post pregnancy

Hi mommies i would like to know if sense of heaviness at the private part is meant that the womb after delivery had drop? Will it be back to normal naturally or I need to consult doctor. I planning to have another baby but is unsure if that affects the pregnancy or not? Malay mommies able to help? Boleh kita mengandung sekiranya rahim jatuh? Ape boleh dilakukan untuk check sekiranya ia jatuh atau tidak? Please help thank you!
