Took a plan b. Am I pregnant ?

I had unprotected sex a day before my ovulation day. I took a plan b 2 hours before my ovulation day. So around 10:11 pm. He didn’t pull out at all. I took a 6 days sooner it’s actually 3 days before I start my period supposedly . I have frequent urination and nausea 2 days ago. Can I be pregnant ? First one is from today the second one is from Monday..could be a evaporation line…
