Now 8 days late...wtf?

So I'm irritated. I'm now 5 days late. I took an hpt one day before af was due and one today both were negative. My cervix is medium to high, soft and feels kind of closed. My cm is a medium to sometimes heavy amount that is like a cloudy EWCM. Im so confused. Its upsetting. I've been nauseous the past 24hrs and lightly cramping. When calculating from 1st day of last AF, I'd be 5 wks pregnant. Going to test again tomorrow morning. Sorry its such a long post. Let me know your thoughts below. TIA

Update: Im now 8 days late. Im so irritated; another BFN. I've also been super nauseous the past 3 days. No vomiting but definitely feel like I have the stomach bug.
