Hi, I'm a 24 years old woman. I had my period on 28th November. I had unprotected sex on 21st December 2022. I tool emergency contraceptive pill within 12 hours. I generally have a 30 days menstrual cycle which is scheduled to occur between 26 to 28th of every month. I also got my period on 27th December which was on time but it lasted only 2 days and the flow was good as usual. I had a home pregnancy test on 28th December which was negative. Later on 8th January(18th day after sex) I took the home pregnancy test again which was still negative. from 13th of January, I was diagnosed with for Urine infection. Later on 20th January, my doctor did Cystoscopy using General anesthesia and I have had many medicine since. I have my catheter still connected. I should have got my period by 26th January but I don't feel any pain and didn't get any bleeding. So I am almost 3 days late to my period. I don't have any other pregnancy symptom. Now I'm worried if I'm pregnant. As I can't do a test now, What are the chances of positive pregnancy?
