Even without duphaston, these are very common pregnancy symptoms. If you were given the duphaston to protect your pregnancy, it’s best to keep taking it. But also get some medicines to help with your other symptoms (diclectin for morning sickness, antacids for gastric discomfort). Also please rest dear. The fatigue in the first trimester is very real. Remember to avoid coffee/tea/spicy food/juices/chocolate now as they worsen your fastric discomfort.
