Low placenta

Hey ladies, so I’m 20 weeks and 1 day, went for my 20 weeks scan today and was told my placenta is lying very low, how many woman had this and there placenta ended up moving during the rest of the pregnancy? If it didn’t, what are the risk with Labour and that? I’m worried as my midwife has concerns aswell but can’t do nothing till labour😩🤔 does it also affect feeling baby movements as I haven’t felt any, just awful cramps😩

This is my 3rd pregnancy
