Still a chance?

So I had spotting for a few minutes on 10 dpo. It was pink. After that ive felt some cramping and I haven't had spotting since then. Just a lot of white discharge. Im 12 dpo now. My boobs hurt a bit and I'm always so tired. Yet my cervix is hard and open. Its moved up though. Its high now. It feels like Af is coming and I feel like I'm out since my cervix is hard and open.
