Having some pain plz help

So I just found out im pregnant couple of days back (super excited by the way)

But I've been having cramps wish I know its normal but I'm also having some pain in my left side maybe some like sharp pain that I feel going down my leg that comes and goes. I have 1 child that's almost 3 but I don't think I remember having this pain..I do work as a server and I am up all the time walking. I'm just hoping this pain is normal sense I've had 2miscarriage plz help =(
