Four days until period

Over the past couple days have had very light tugging cramps, extreme nausea, I used to guzzle water but now water from different sources all taste strange (city water at work, well water at home and at in-laws). I could sleep alllll day long. Due to nausea I'm not hungry at all 😐. No sore boobs or heavy cramps which happen right before my period.

I haven't tested because right now I only have a digital and would rather wait to take it. I'm 10dpo today.
