Wtf is wrong w my leg😭!

I’m not looking for medical advice, just curious if I should be concerned .. haven’t experienced this before. Currently 18 weeks pregnant & one leg has very visible & bulging veins. My other leg is perfectly fine & I have no swelling or anything..

Edit ; I already said I wasn’t coming here for medical advice lol, learn to read. I’ve just never experienced this & was wondering if anyone had an inkling. Was not looking to get a diagnosis & obviously I am going to consult a dr. It’s 8pm.. no doctors are available. Relax.
