Plan b!
You should really know your body when it comes to ovulation girl it has helped me so much 1 1/2 and still no baby. 9 days before is still a good enough window if you know your body and when you’re ovulating but if you don’t then yes I would do a plan B but keep in mind plan B have a weight limit of 155 pounds or less for it to be more effective “ “
I would take a plan b just to be safe it’s always when you think it’ll be okay that it happens lol!
