Is being super thirsty a symptom?

Laura • After many long years I`ve found the love of my life n I`d love to give him a family❤️
My AF is due 9/19. On 9/9-9/12ish I had weird spotting. I've been SO tired, bad back ache, bad headache, nauseous, sensitive to smells as of today and VERY THIRSTY FOR COLD COLD DRINKS! Any suggestions?? Is this Pms symptoms? I've never had that kind of "spotting" n I feel like I have the flu so bad. Even my bf noticed I'm sleeping all the time.
