When did you feel your first symptoms?

I suspect I’m pregnant but my period isn’t due for 6 more days. I’m suddenly so unexplainably tired. I had to go to bed at about 7:30 pm last night and still napped at work and I’m feeling a little bleh when I eat (not throwing up tho) . I’m also sooo bloated and have had a horrible headache for two days that just won’t go away and I never get headaches. I also am getting this weird little twinge crampy feeling in my lower right groin/abdomen area which is odd. I know my period isn’t due yet but I really think I’m pregnant I just feel so different. When did you feel symptoms?
