What are my chances?? ?

My period was on the 21st ended on the 25, I have a 25 day cycle, my husband came in me the 27 and the 1st, what are my chances getting my period, could I be pregnant? This is our first time wanting a child, we have been marriaged almost 2 years and have decided this is our time to have some children, I do smoke but have been cutting back and will stop but every time I smoke a cigarette I feel sick after I have also been having a little pain in my left ovary? I've never had that before its not a horrible pain just a little cramping pain? Thanks for the help ladies and gents!
