Risk of pregnancy after fertility window?
I had unprotected sex on Feb. 17. I don't keep close track of my periods, but I know my last one ended around Feb. 2nd. Assuming it had started about a week earlier, I calculated my fertility window to be between Feb. 5-15. I don't know a whole lot about fertility windows, but I know that anytime you have unprotected sex there is a risk of becoming pregnant. I was wondering what my chances are if I had unprotected sex within a couple days of when my supposed fertility window would have ended?
