Thank you all SO MUCH for your replies. I am thinking that I am just having a raging case of PMS!

We are not planning on having more kids, but if we were pregnant, it would still be a blessing! My sister has some extra pregnancy tests, to I think I am going to talk her into bringing me a couple, just in case! I know this sounds nuts, but my DH keeps saying stuff about it and when he did that in the past, he was always right.

So, I guess we shall see!
