Leg/ Back aches pregnant

T

4-5 weeks pregnant. On progesterone suppositories (even though my progesterone is high), but I’ve had lower back aches coming from one hip to the other. & some pains in my legs/knees like growing pains. Is this normal?

I’ve had two miscarriages & one ectopic so I worry about any little thing. My first blood draw did triple so good news. But anyone else have this??
