One leg swelling ... 34 weeks

Has anyone had any one leg swelling and it being ‘ normal’ I have really bad swelling in only one leg and foot and ankle , I have read up that it could mean a clot but I’m not in pain at all it’s just uncomfortable because it’s really tight ! Anyone had this and it just being normal swelling ? Or has anyone had this and it be a clot but without pain ?

Thankyou !
