Advice

Hi ladies this is my first post, I need your advice. I had sex 7 days before ovulating, and had to take the morning after pill after unprotected sex that night. Then, two days later I had sex again with another oopsie, but no morning after pill. I felt like my period was coming my breasts REALLY hurt about a week and a half before my supposed period which is now three days late. My breast tenderness is gone. I feel a little nauseated briefly in the morning, but don’t throw up. Could this all be related to the morning after pill? Advice or Experience like this? Thank you
