Possibly pregnant?

Ashlee
So i want everyones opinion before i go get a test. Im having these weird feelings on the lower lest side of my abdomen, by my left ovary. My areolas are darker. My gums bleed when i floss, which is new. Im so tired now. My breasts feel and look fuller. I feel nauseous in the morning and at night. I just dont know what to do. Im scared to test because the father is out of my life now. Please give me your opinion on what i should do. Am i crazy or possibly pregnant?
