Hello, I have gone through your query and understood your concern. You should first confirm pregnancy, if positive, follow it up with a trans-vaginal sonogram to locate the gestation sac and the age of the pregnancy and then get properly guided induced medical abortion. Inadvertent use of abortion medication can lead to complications. Her symptoms of tiredness and abdominal pain are due to the medication which induces uterine contraction. The discharge also is a consequence. Please visit a specialist as soon as possible for further management. Also, please remember, unprotected intercourse taking place during the safe period of the menstrual cycle does not cause conception. Hope your query has been clarified. Take care.
