After taking Escapelle/Postinor, there are a few signs you can look out for. If you experience side effects like nausea, breast tenderness, or changes in your menstrual cycle, it could be an indication that the pill is doing its job. Additionally, if you get your period within a week of taking the pill or around the expected time, it is generally a positive sign that the pill has been effective (in preventing pregnancy). If you are still unsure, it is best to take a pregnancy test about two to three weeks after taking Escapelle/Postinor. Remember, if you have any concerns or questions, it is always a good idea to consult with a healthcare professional for proper guidance and peace of mind.
