Ugh I'm so mad!!! I looked everywhere and my new pack that I was supposed to start tmro is missing.   My doctor only gave me 3 packs and I lost the 3rd one so idk if I could gEt another Refill. Has this happened to anyone?? What do I do??? I heard they're $50 and I really don't have that extra money right now
