Please help.. Restless legs!

Sky • Expecting baby boy due June 18th 💙
I'm not sure if this is pregnancy related but it's only just started happening these last 3 days, at night when i get in bed, my right upper leg kinda just above my knee starts to ache and tingle and I get sharp pains and I can't get comfortable I get so restless so feel the need to walk around its so irritating! It's so hard to sleep. Has anyone else had this? My AF is 5 days late and I have had other symptoms. Going doctors Monday to test :)
