Praying Salah outside home for women

Assalamualaikum I live in a country where only 1/100 mosques have space for women, and there are rarely any prayer spots. So, when I am outside home, and there are no washroom to do wudu and no proper place to pray as a woman, what do I do? Also please reply a result with Quranic or hadithic reference since I am a Sunni Muslim.
