Hi, may I answer your health queries right now ? Please type your query here... I have a 25day cycle,my periods started on 11th July 2010 and i had sex on the 18th July then again on the 24th July but took Postinor 2,both tablets at the same time,that was one hour after sex,on 25th July i started bleeding and it continued to 27th July,on the 31st i had sex again. I'm confused coz i'm now pregnant.
