The ds in Danish are usually (with a few exceptions) silent after certain letters, including "n", but I think it takes time and a bit of patience to hear the slightly subtle "en" on it. Just keep practising and you'll get there in the end
Kvinden is pronounced quite similar to how you write it whereas Kvinder is pronounced with an 'a' at the end. So you pronounce it like 'Kvinda'. Kvinderne is pronounced like 'Kvindane'
