Morning after pill

Plan B was taking during my ovulation. I actually didn’t know it doesn’t work during that time. If I am pregnant all is good. It’s a wanted pregnancy, just wanted to hold off another year. Anyway, within hours I felt bloated and dizzy. Symptoms went away until 5dpo. In the middle of the night I got nauseous. The next day I had cramps, sensitive nipples, urinating a lot, burning belly. I feel pregnant. I know morning after can give you similar symptoms but I thought they went away? 6dpo same symptoms but wanted to add the smell of cooking chix made me ill. I’m on 7dpo and I feel much better. Is this all in my head?
