hello i took glomid for 5 days after period , then at day 10 my Dr did an ultrasound for me and she said my follicle is around 2 , so she gave an injection i think it is called chomioron 1000 units , and she told me to start duphaston at day 15 till day 25 , how can i make sure that my symptoms are from pregnancy not from duphaston , like nausea
