Going out of my mind

I'm 8 dpo and all I can think about is how crappy I feel. I have a mixture of constipation and diarrhea the last 3 days. Some major cramping going on around where my ovaries are and in my lower pelvic area. All I want to do is sleep. And I've had a headache last two days. So hard not to try to just automatically assume things so I'm just going to assume that I am having PMS until it's time to test v😭.
