Ovulation

Hello everyone I’m in a dilemma and I feel really bad about the situation but long story short my period was January 6th 2020 and my ovulation dates from what I’ve looked up or from 14 January to 21 January I found out I was pregnant my due date is October 12th I hooked up with someone else on January 25th of 2020 could that guy possibly be the father or am I just crazy? Help
