Can some people get pregnant at any time of the month???
That’s because most people don’t know exactly when they ovulate, and it can be at any time of the month. My periods were coming every 35 days, and the month I got pregnant I ovulated on the 30th day of the cycle (rather than the 14th day, as the theory would have it). You only ovulate once (actually, I think some people can ovulate more than once- I’m sure I’ve heard that, but I imagine it’s rare), and to get pregnant you need to have sex within 2-3 days of ovulation. It’s just a matter of knowing when that window is, and if you don’t know and you don’t want to get pregnant, then you need to use protection all the time.
