Too many symptoms

I believe I’m 11dpo . I’ve been having like this ache in the middle of my pelvic area . Like a cramp but not sharp just dull . Almost feels full like . It’s been this way allll day . Headache , irritable , frequent urination, very sore tender nipples . I took a test last night it was negative , also the day before . I decided to pick up a few more test just now . Of course I want to be pregnant but a part of me have seen negative so much I believe I’m out again this month and I’m probably preparing for AF . Though I never have continuance of symptoms up til my period . So ladies have you experience this at 11dpo and was positive
