Maybe I’m reading too much into it?

So I previously posted that on Monday I would get random hot flashes flowed by Immediate nausea and vomiting (about 8dpo) and then Tuesday I was all good! Then weds morning I threw up again! Felt fine through out the day. Definitely noticed when I take bites of something’s my stomach is like NOPE before I even try to chew and swallow over the past few days. I did take a early test yesterday and it was negative 😒 today I’ve had WAY-more tender breast, not much but slight nausea and when I tried to eat a fruit and nut granola bar, I couldn’t get past the first bite again. Do I still have hope? My period is supposed to begin Sunday! Today is cycle day 25. Thank you in advance for yalls experiences!
