I am 21 years old , I had an intercourse the day after my periods got over and unfortunately there was a failure in the safety measure , so I freaked out and took a ECP in 2 hours after the intercourse , also I took another pill in the next 12 hour.. and to be safe I took the 3rd one the following 12th hour , I was not aware of the side effects , but no after 7 days I get bleeding and I had nausea for 3 days ? What are the side effects and will my bleeding stop?
