Im scared

So my bf and i had sex on the day after the last day of my period. I remember i still had brownish discharge that time. We used a condom and he came outside of me with a condom on.

However, i am worried that i might be pregnant since I haven’t seen my egg white cm or felt any ovulation symptoms. Is it possible i ovulated right after the last day of my period and then something fertilized? Or maybe my ovulation week is adjusting? Seeing my egg white cm during my ovulation week is assurance for me sknce it means nothing was formed last cycle like a pre-sign before my actual period
