Help!?

Jo
Ok so I'm 4/5 dpo, I have dull cramps in my abdomen, and pains in my left side. Creamy , sticky cm, very tender boobs, I've had some itching in my nipples today. Slight wart burn. Headache for a few days. And just general feeling of unwell. My period isn't due until a week Saturday. My question is...how can I stop myself stressing out, when can I test...and does it sound like pregnancy (Anyone else having these symptoms and got a positive)
