hi there, bright yellow urine may be due to the vitamin tablets that you have been taking or may be due to concentration of urine due to decreased water or fluid intake. White vaginal discharge
which is asymptomatic and non foul smelling in mild to moderate amount is quite normal, and the stomach ache or cramp can be due to prementural syndrome. There is essentially nothing wrong with you as per your symptoms and I would suggest that you take adequate nutritious diet and plenty of fluids along with minimum 8 hrs of sleep per night and you will feel much better. Take care.
