Could I be pregnant if I took the emergency contraceptive Unwanted 72 within an hour of having sex in May, had two heavy periods since then, but am now experiencing breast enlargement, lower abdominal pain, and headaches?
It is highly unlikely that you are pregnant. Taking Unwanted 72 (levonorgestrel) within an hour of intercourse is extremely effective, and having two heavy periods since May is a very reassuring sign that you are not pregnant. The symptoms you are experiencing now, like breast changes, headaches, and abdominal pain, are likely due to normal hormonal fluctuations, stress, or PMS rather than pregnancy. However, for your peace of mind, taking a simple home pregnancy test is the quickest way to be absolutely sure. Please consult a healthcare professional if these symptoms persist or worsen.
