My period started on the 23rd ended around 28-29th had sex today the condom didn't break and there was no ejaculation, can i be pregnant?

Yes: There's always a chance you can get pregnant if you have intercourse, even if the male doesn't ejaculate. There are sperm in the fluid that is present when the penis first become erect - plenty of them. I you used a condom the entire time and you only had contact with your partner while the condom was on, then your chances are much lower, but if you have intercourse, there's always a chance.
