Hello girls! I'm 25 weeks pregnant. They told me to wear a bandage, but in pharmacies I couldn't find one, the size is wrong and they don't even know what to recommend. I went around all 15 pharmacies near my house, but unfortunately... If you have any recommendations for brands, please let me know with photos. I've never worn such a bandage before and I'm afraid to buy the wrong size and quality. Thanks ?
