Is there still hope?????

11dpo heavier bleeding started out very little spotting last night that stopped after a few bathroom trips. This morning little bit of brown and pink blood but heavier than last night. Fast forward to now little tiny clots brown and red/pink blood and heavier cramping mostly in back some up front but lower than AF cramps usually are. Sore boobs super nauseous, I'm a smoker and had one cigarette today cause I feel so sick and the thought makes Me wanna vomit. 3 days till AF cycle is always normal, am I out or do I still have hope? If so when can I test to get best result?
