New to all of this

Hello. New to all of this pregnancy stuff. I’ve got the following signs HOWEVER I’ve only gotten NEGATIVE tests.

-11 days past period

-Weird smelling cm and sticky/clearish

-I’ve peed 9 times today starting at 7 am. (Every hour on the hour almost)

-SUPER tired

-vagina area is dark purple in color rather than pink

-SUPER sensitive nipples (not really breasts. Just nipples)

- cramps like I’ve been doing abdominal exercises

- diarrhea

- acne

-backache

-headache

I just don’t understand why I’m pulling in all the (-) tests and no (+)
