Aching on left side of leg and feet...is this normal during pregnancy?

I’m currently 19 weeks and 4 days. Since yesterday my leg, knee, feet, ankle are aching. Especially whenever I get up after sitting, it really hurts. Is this normal during pregnancy?

With my first I didn’t experience this...I just got sciatica pain towards the end of my pregnancy.

For those of you have experienced this, what helped you?
