Could there have been fertilization on the 5th day of menstruation?

Could there have been fertilization on the 5th day of menstruation? The situation was such that a few days ago we had sex. First, when putting on a condom unless he touched a member with one finger and then put a condom after moments he introduced the member into the vagina. Then after ejaculation outside the sheath, he changed the condom to a new one, pulling very carefully, rubbed his hands into a handkerchief, but no longer a member, and put on a new one again. After 2/3 minutes he again introduced the member into the vagina. The question is do I have to be afraid all month that fertilization could have occurred (my cycles are 27/28 days so according to the calendar until fertile days I still had a full 3 days and a few hours)?
