Is it possible?

I had my miscarriage nearly 4 months ago. I had some symptoms before I found out but nothing crazy. Hubby and I only baby danced once but it was the day before I ovulated. I’m 5dpo and i know it’s super early but I’m experiencing weird things. I still am getting very dark positives on my opk’s. I feel very nauseous today. And yesterday, for no real logical reason, I was crying nonstop (especially while hubby and I were watching “Shrek Forever After”). Could I possibly be pregnant? ( p.s. tww really sucks!)
