<s>[INST] I had unproteted sex on 20th, 21st and 22nd April. I took emergency pill on the afternoon of the 22nd. I am sure /i ovulated on the 20th because I can feel when and which side i ovulated on each month. I suffer from rosacea and have taken one tetralysal tablet each evening for the last 2 days (8 days post ovulation). I am worried that the pill may not have been effective, i have a lot of pregnanacy symptoms (rosacea, right side lower abdominal ache, general cramping and since the 23rd have had increasingly tender breasts with sensitive nipples). Im now worried that if the pill hasnt worked, that my baby will have deformities because of the tetralysal. What is the liklihood of a) me being pregnant and b) my bay having deformities? Thank you [/INST] Welcome to Chat Doctor, Betrayal belongs to tetracycline group of antibiotics which can effect the action of emergency pill. There is a chance that the emergency pill may fail. Betrayal is not supposed to be taken by women who are pregnant as it may result in malformation of the fetus. I recommend you to wait for your next period. If you miss your next menstrual period do a urine pregnancy test. If it turns out to be positive visit your gynecologist who will take a detailed history and decide on the pregnancy. Hope that answers your question.  Chat Doctor.  </s>
