Perhaps but unlikely: The fertile time in a cycle is actually quite variable. As many as 3% of women ovulated when they expected their menses, so it is possible. The window of fertility is actually from about day 6-21 as at least 10% of women were fertile on any of those days. So, always use good contraception unless you do not mind getting pregnant. A pg test can tell you if you are at least 12d post-ovulation. Best.
