One more, one more, one more...

My husband and I have had our share of trials in our 11 years of marriage, getting through college while raising kids, loosing our first born, miscarriages and successful pregnancies,even raising relatives children due to their drug use. I feel like I'm done having children, I've got 4 children in my home as it is and while we are considered middle-class, of course we live pay-check to pay-check. He wants more children. I honestly can't change his mind, although Ive tried. He's wanted a lot of kids for as long as I've known him. Everyone always said "just wait, once you have one or two he'll realize that's plenty" but he's not like that at all. He LOVES the kids and if anything wants even more. I've pretty much agreed to one more for now, but had no intention of getting pregnant this year (my youngest just turned 1). Now here I am, searching the internet because I might be pregnant and have never had one unplanned. ugh. UGH UGH UGH>... I need to turn this positive in my mind, but I just can't right now. The faster this week goes by and I have a real answer, the better. Has anyone else delt with a pregnancy with bad timing? I know many must have, but we've planned out, down to the week I'd be due, when I wanted each child to arrive and got pregnant accordingly. Lol, I get pregnant according to what I want that childs birthstone to be. Needless to say, I have zero problems getting pregnant, although I've had a couple problems staying pregnant before. I'll be testing ASAP, like starting at the 6 days before my missed period and every day until my period arrives or I get a positive!!!!
