Pregnancy dreams?! I’m freaking out!

So in the past week I was really stressed out about being pregnant, yesterday I got my withdrawal bleed from my pills, normal flow. I was relieved. Last night I had dreams of fish, and actually giving birth to a baby. Was this related to all the anxiety? Or maybe I shouldn’t be so relived? I saw a few people who were pregnant on Facebook throughout the day? Is my mind messing with me? Can you have a normal withdrawal bleed and still be pregnant??
