Hi, According to your symptoms, you could have suffered from a transient disturbance of the blood pressure which may have settled with rest. Dizziness is common even without any other complications in pregnancy. As you are anemic too, it could be more often. The symptoms may get aggravated as pregnancy advances. You should have regular follow-up and monitor your blood pressure regularly. You should also take plenty of fluids and a healthy diet apart from nutritional supplements to improve your general condition. I did not get what you meant by veins-at which location and when. Veins are always blue and in pregnancy, veins over the abdomen and the lower extremities get prominent. Please get further suggestions from your doctor. Take care.
