Hello girls, I had an ultrasound recently at 6 weeks, there is a risk of miscarriage. Before that, there was one spontaneous abortion. I consulted with a gynecologist, she prescribed Refaem 200mg and Refaem 100mg. Could anyone who has already encountered this drug tell me how they felt and did they gain weight? I'm very worried about the baby.
