Can I get preggo now?

I am on day 10 of my cycle, I had on day 6,9 and 10, what are the chances of me getting pregnant? I have been on a normal cycle since I have had my first child and my cycle is 27 days faithfully. I have 2 daughters ages 3 and 5 and had an abortion (regretting everyday) in Apr of '10 so fertility has never been an issue.
