Ovulation

How likely is it to get pregnant during ovulation with Pre-Cum? My husband and I have been using the pull out method and accidentally did it the day I ovulated last month and this month my period was very light basically almost spotting I didn’t get any cramps or symptoms I usually get when I’m on my period. I spotted for 3 days and it was light red with a tint of pink and brown. I took a test 2 days ago and it was negative I’m not sure if it was too soon to take a test? Please help, I’m stressing dying to know if I can possibly be pregnant 😬
