Hello Doctor, I am an 18-year-old female. Yesterday, I had unprotected intercourse . My partner is confident that ejaculation did not occur inside, but I am extremely worried about the risk of pregnancy due to pre-ejaculate (pre-cum). ​I am concerned about the safety and side effects of emergency contraceptive pills like i-pill or Unwanted-72, but I want to take the most effective step to prevent pregnancy. Please suggest me what should I do. Help me doctor please.
