Yes, this happened with me and my girl once, came here, read up on other sources and deemed it unwise for her not to take a Plan B
if we weren't ready for a pregnancy
Given the average period(bleeding) is 6 days, 2 days after made it day 8, on a 28 day cycle you would release an egg around day 12-14. Sperm can survive long enough to inseminate.
My advice is to take a plan b now while there's still time.
I'll post links to our questions
