What are my chances of being pregnant?

Hi there, just wondered if anyone could give me some serious advice about my chances of getting pregnant. I had my period on 1st May and lasted for 4 days. I calculated I would therefore be ovulating around the 14th May. My partner and I had on the 5th, 9th, 11th, 12th and 14th. What do you think my chances are? And also, when would poss be the earliest I could test? Thanks guys and baby dust to all others TTC :)
