Muscles pain/aches

I’m 32 weeks preg going on to 33 weeks in 3 more days. I’ve been have frequent aches when I sit down too Long or getting up after I lie down which I expect is normal as baby Is getting bigger. But most of the time, the right side of my leg near the below butt area tend to ache more esp when i have to put pressure on the right side is either too painful or my right leg will be too wobbly to even rely on. Is this normal ?
