Maybe a weird pregnancy sign???

Okay, so I am 5 days late for my period ttc, I took a test a couple days ago and it was negative. So I am planning on testing again. But the past couple of days I have been craving water, which is weird for me because I usually don't like water but now it tastes so good to me I can't get enough. I've always been a very hydrated person other wise, but I do drink a lot of pop (bad choice I know) and I honestly can't even stand the taste or carbonation here lately. I've also been having a lot of nasal congestion but no other cold symptoms. Are they maybe pregnancy signs that I just haven't ever thought of or am I just too hopeful.

Please answer in any way possible I'm trying not to think about it too much so I'm hoping to maybe get some answer that will stop making me think about it too much.

BTW I have had light cramping, but no other signs of pms and the cramping comes and has came and gone for a couple days now. Nothing like my usual period cramps. And my periods and cycle are very very regular.
