Hello I share your concern Pinkish vaginal discharge might be related to pregnancy, infection or inflammation of the urogenital tract. in my opinion if you are suspecting pregnancy than you should immediately consult a gynaecologist for transvaginal ultrasound for confirmation whether pregnancy is there or not? Apart from ultrasound you can do urine pregnancy card test which can be done at home with early morning voided sample. Meanwhile maintain good hygiene and have well balanced and nutritious diet multivitamin especially folic acid supplements are advisable. Have lots of fresh fruits, vegetables, egg in your diet. Drink plenty of fluids Hope I could answer your question, please feel free to ask for further clarification. Best wishes
