Can I get pregnant if I had unprotected sex on my first day of ovulation??

Yes, how are you tracking ovulation to know you really are

yes, how are you tracking ovulation to know you really are because I check my chart

Not a phone or online chart that merely uses the time of your periods, You will need to be using a actual ovulation calculator and/or including tracking your temp and other factors.

The charts merely assume standard timing which many women are not.
