Are these varicose veins or a blood clot?

👩🏻

I am 23 years old and am 7 months pregnant. I golfed today with my husband and family in a scramble, and I started feeling this stinging around my ankle. Almost like I cut it shaving or something. The pain has gotten worse and now I notice these veins bulging. Idk what’s going on but it hurts! Now I am feeling throbbing and aching around the area.
