Hi,

I'm 31 and my last period was due on 10/10. (and actual last period happened on 4/9-9/9)

But it didn't happen until 21/10. I took pregnancy test and showed negative although I didn't think I was pregnant. 

Me and my boyfriend had sex and condom broke. So I took emergency pill the morning after (within 12hours). That was 22/10. 

Today's 1/11 and period hasn't come yet. I know it can delay the period but skipping almost 2 months and negative pregnancy test? Can it happen?
