Hi all! I last had my period starting on October 5. I had unprotected sex on Saturday, the I expected my period.. I still haven't had it and now it's Friday. I know you can get pregnant from unprotected sex and that the pull-out method isn't guaranteed but he did pull out.. Also, I have a yeast infection that my doctor thinks came from taking antibiotics.. The last time I had sex before Saturday was on September 22.
What are the chances of getting pregnant the day before/of your expected period? I've never been a week late and just want to know how much I should worry.
