What days of my menstrual cycle am I most fertile?

Patient: My first day of my last period was april 4 2014 , i want to kno my fertile days and ovualating days in order for me to get prego because i think im prego

Doctor: In any menstrual cycle ovulation occurs 14 days prior to the next periods. So in a 28 days cycle your ovulation could h ave occurred around 18th of April so you will know if you are pregnant only after 2 May and that only if you miss that period. Good luck if you are looking forward to be pregnant.
