I ovulate on the 25 of this month and I just had unprotected sex is there any way that I can become pregnant?

Sure, of course! Having sex around the time of ovulation is the best known way to make a baby. Since today is the 23rd, the sperm will swim to be in position, eagerly waiting for the egg's arrival. A primary care doctor or an ob-gyn doctor can help with family planning, if one is not wanting to raise a baby at this moment.
