I am 21 years old i took unwanted 72 on 14 feb just after 3 hours of unprotected intercourse. I have my due date on 5th march. I got spotting on 21st feb and it has continued for about 8 days now and on 8th day heavy red flow is visible. I have history of irregular periods and PCOD. Is it ok or a serious cause of concern....i had jaggery nd jeeru after which red flow started. I am having light abdominal pain. And now as the red flow has started i feel like its a period. Is it cause of concern and how long will it last.
