(First of all, we are not TTC. However, we have both discussed and agreed that if something crazy happens, having a surprise baby will be just fine.)

I track my ovulation vigorously. I even use ovulation tests. I do BBT and CM monitoring. Suffice to say, I know exactly when I ovulate each month, and I know exactly when my period is due. Thankfully I have very regular cycles so these methods have been foolproof so far.

We use condoms within 6 days before ovulation, and 2 days after. The rest of the time, we go unprotected. We haven't had any reason to be worry about a surprise bundle of joy.

But lately, I've been seeing all these "OMG AM I PREGNANT!?" posts on Glow lately, and there are MANY women on here saying that it's possible to get pregnant at any point in your cycle. I don't see how this is possible, unless you're unaware of your ovulation date or aren't aware of how long sperm lives in your body/how long an egg is viable.

Is it really true? If so, how on earth does that happen? All the studies I've read, it's only possible during your fertile window.
