9 dpo.....all in my head???

Considering testing tomorrow (10dpo) and Sunday (11dpo) but afraid of a negative. Since Tuesday (6dpo) I have been super tired. 8 hrs of sleep every night and can't keep my eyes open during the day. Have dozed off at work a couple times....totally not safe but I really had zero control of it. Have been crampy and achy and feel like a softball is in place of my uterus. Lower back hurt for a couple days after that. Can't tolerate the taste of bbq or olives or water. Yesterday I couldn't eat anything and today I couldn't eat enough. Ended up getting sick on my way home from work and again after I got home. Have had diarrhea on and off all week. The tww is killing me.....idk what to think right now. My SO swears I'm pregnant but I'm not so sure. Maybe so long of a time trying and I won't let myself get excited or maybe denial....idk. Any input ladies?
