Since no ejaculation happened and the condom was corrected before continuing, the pregnancy risk from this encounter is low, though pre-ejaculate fluid can occasionally carry a small number of sperm. Your period isn't overdue yet going by your usual cycle.
Next Steps
If you want to lower the risk further, an emergency contraceptive pill works best within three days of exposure, so today would still count. Track your cycle and take a home
pregnancy test if your period hasn't started within the next two weeks.
Health Tips
See a gynaecologist if you miss your period or notice spotting, cramping, or anything unusual, so this can be confirmed properly.
