With a 28 day cycle when imputed into the ovulation calculator it shows your fertile period from May 9-19th. So yes you have a chance wait till your next period is due and take a test if AF doesn't show
yes you have a chance of being pregnant as long as it was around the time you were ovulating.. since you have a 28 day cycle if you add 14 days to the start of your LMP that shows when you are ovulating and normally you get pregnant 1-2 days before or after. Sperm can however live up to 5 days in a good environment. I know some girls who forgot to take their pill one day and got pregnant, so yes you do have a chance
Im not sure when i ovulate but I have a 28 day cycle
You need to know when you were ovulating. How many days is your cycle? You ovulate 14-16 Days BEFORE your period. If you had sex during your fertile period then yes you have a chance of being pregnant.
