Could this be a symptom?

So I am now 8dpo and last night/this morning I woke up at roughly 1-2am I woke up with extreme nausea (I hate being sick to I did everything I could to hold it in) This lasted until about 6am when it eased off. Now it’s mild nausea that comes and goes.

I thought it was too early for these symptoms. I also have very painful nipples, and fatigue (but that could be the 32 degree heat in the uk at the moment) 😂

I know it’s long but what do you think? I don’t want to test to early and stress myself out.
