Girls, hello?

Girls, hello ?. I have some strange jolts that feel like someone is pulling on my uterus with a rope and pushing it down, there's pain but bearable, I don't understand what it is, maybe it's baby movements or is this even training contractions? It's been 3-5 days already, especially when I sit or lie down. Maybe someone else has had something similar, I have an appointment on Wednesday, but the midwife in the clinic is very young.
