So on this past Sunday I was meeting up with a friend. I was late on my birth control because I was at work and took it late. When i hung out with my friend we had just Bacardi. He never ejaculated inside. And when I got home the same day I took the day after pill "Ella." All of a sudden in the late afternoon I started feeling nauseous (feeling started in my gut) and also im roughly in the 200s. Should I be concerned for pregnancy? Or am I overreacting?
