How high is the chance of pregnancy if I had unprotected sex 4 to 5 days after ovulating?

My husband and I had intercourse on the 7th of Feb.  He did actually *** inside of me, and now I have been trying to figure out the chances of pregnancy
.  I am pretty regular and get my period on or around the 18,19 or 20th.  From what the ovulation charts show, is that I would have been ovulating and really fertile on the 3rd of Feb, so what do you think the chances of me getting pregnant would be if again I had unprotected sex 4 to 5 days after ovulation.  
One site said that there is absolutely no chance!  and another said maybe 5 %...  
Doe's anyone know the true answer to this???  Also that day before we had sex I was already feeling cranky and my breast were tender, I usually start feeling these symptoms two weeks before my period, so I know that my body was already letting me know that my period is going to come in a week or two.

unless you have sex within 72 hours of ovulation ( before or after) i'd say there is no chance as that's how long sperm can live for in your body. if you're trying to conceive, here's hoping your ovulation actually occured just a little later than you thought. and hmmm, if your body was givin you signs that you were gonna come on your period in 2 weeks, isn't that perfect ovulation time? a little help on that one please

In perfect conditions sperm can live up to 5 days. However, if you ovulated 4-5 days BEFORE you had unprotected sex then there isn't anyway that the egg survived. Sex before ovulation can lead to pregnancy because sperm can live for a couple of days. However once the egg drops you have about a 24-48 hour window in which to actually conceive.

Ovulation is the time in which you can become pregnant. If you had sex after ovulation then you will not conceive. The egg lives for about 24 hours after it has been released from the ovary.
