(reposting this here b/c I didn't get too many responses in other forum)

So we had unprotected sex this month. Not really TTC right now - but fine if it happens.

Anyway, having all the symptoms - sore boobs, hunger, tired, cramps, etc.

So I POS this morning even though I'm still 9-10 days away from my period.

I couldn't stand not knowing anymore.

And I could see the faintest of faint lines in the positive window. So I put it away to show my boyfriend later. When I took it back out it was positive!!?!?!

So we just had a big talk about another baby!
And then I POS - a new one. And it's totally negative.

How can that happen?

I mean - what would have made it turn to a blue line if I'm not preggo?
