Butt-ache at week 10

Hi, I’m currently about 10weeks pregnant and this is my second pregnancy. Every time I sit on any type of chair (cushion or non cushion) I feel pain on my butt after a while. N I had to struggle to stand up. This is exactly what I experienced when I was in my 3rd trimester during the previous pregnancy. Is it normal that I experience such pain so early on in my pregnancy? Has anyone experienced this in first trimester too?
