Am i at a high risk of getting pregnant?

ok so i was on birthcontrol for a month and it ended on the 19th of march due to things getting switched around. anyways, i had my period at the end of my white pills which lasted from the 15th till the 18th...my boyfriend and i had unprotected sex and the pull out method was not used either....i believe you start ovulating 2 weeks before your next period which would be today (correct me if im wrong). and i just want to know if im at a high risk of getting pregnant.....last time this happened was around october of 2012 which resulted in my now 9 month old daughter.....help please?!?!
