I am 4 months pregnant. my doctor has suggested me to take duphaston and susten. In my first month I consulted to other doctor.she told me I should take duphaston till 3 months but now my new doctor is still continuing the medicine. 3 days back I stopped the both medicine and I am facing a problem.my urine colour has changed in light reddish colour. What is the reason behind this and what should I do.
