Girls, share your experience if you took Dufazon up to 12 weeks? My gynecologist is not worried about it, prescribed Dufazon on week 5 until 12, said if you want to get pregnant and trust me then take it without extra questions? I took it but there's such an impression that they inflated me, and weight increased unjustifiably (appetite decreased, eat little by little, and weight increases) I listen to my body and there's such an impression that I'm a sponge that absorbed a lot of water and swelled ??? The doctor says this may be, now interested in how others had it and how it went after?)
