Had a dream last night that Dh made us both dr appointments and I was mad because I don't have to go for like three years or something. (I think this came from Dh telling me last night he had a dentist appt today)
So I'm there and this doc is like "are you sure you aren't pregnant?" And I'm like yeah, pretty sure. Well he's like I'd like you to take a pregnancy test anyway. So I do. Now mind you, I've never seen one IRL so my dream made this all up. After like a minute, it bounced around a percentage of pregnant/not pregnant. The final percentage was like 55% not pregnant, 45% pregnant.
That'd be kinda neat if that's how they worked.
Granted, it has been a while...but I'm pretty sure it's an all or nothing determination.
