I’m 7weeks pregnant . Went for an ultrasound and doc could only find the gestational sac and yolk sac and told it looks like 4-5weeks . Had no cramp or spotting and periods was regular before. She prescribed duphaston 2 times per day for 3weeks. Since taking the medication stomach cramping very much Everyday and also brown spottings which was not there before the prescription .is it safe to continue with the tablet or stop and see the doctor?
