Myth?

I was talking with my SIL a few weeks back about TTC. She said " you know how after you get done having sex, the semen leaks out?" Well yeah. She said "well both times I got pregnant it never leaked back out, that's how you'll know."

It has always leaks back out (ttc for 6 months) and I didn't think much of what she said.

The last two night it hasn't leaked back out... now it's got me wondering, haha.

What do you ladies think?
