Boyfriends perspective - it's so simple!

I've had this weird pain in my stomach and I told my bf about it. So he asks "oh wow do you think you are pregnant?" I, surprisingly keep my cool as HE knowingly missed all of our peak days, I responded with "no baby, how could we if we missed all of our days??????". Oh....he said "you are silly sometimes, that's not how it works. Who cares about the days, when you get pregnant it just happens." Wow. That's all I have to say. Wow. He is 35. He knows better ... Or does he.....
