I had sex on my fertile days which was the 23 and 25 and my boyfriend ejucluated inside of me can I be pregnant?

Quite possibly. You will need to get a pregnancy test. Test kit from your drug store should be extremely reliable reliable on first day of next expected menstrual period, and quite reliable as soon as 4 - 5 days before first day of next period. Good luck. In future suggest you use birth control, best discussed with your primary care or gyn dr.
