Do I have a good chance of getting pregnant?

Ok so Hi I am TTC I have a 28 day cycle it is very normal,had my period 15 days ago (15th), and I had monday the 25th, tuesday the 26th, weds 27th and friday the 29th. I have been having some cramping under my bellyon but that could be due to ovulation right? So My question is do I have a good chance of getting pregnant? Thank you
