During intercourse the condom just got torn so for protection I took a 72 unwanted pill within 24 hrs. After a week I got withdrawal bleeding and after 10-12 days or a week before my actual period date I got periods. But I am having light bleeding and the period is shorter. And am facing issues like pelvic pain, frequent urine, pain and burning sensation during urine. So I am very confused about this. Is there any chance of pregnancy?
