Hi can someone keep me calm

so i had unprotected sex with my bf during my period. it was on the 4th day of my period there was still alot of blood (i know) we have been pulling out for 5 years now and I do trust his pull out game its just that there are times that I get all anxious about that SLIM possibility. my cycle is 30-33 days so Im pretty sure im not ovulating a week later after my period so im pretty itsby bitsy safe right?

(p.s I kinda trust my bf and his pull out game but there are just times that we were in the moment and he forgets to wear condoms.)
