Lucky Number 7?

I am pregnant. It's four in the morning, rain pouring down, and my third pee test shows a dark second line. It's just me in the dark with a speck of baby, maybe two? growing inside me. Holy Shit. Yesterday was my first positive test, a faint line, and then one of those digital tests that says clearly "Pregnant." Pounding heart, jittery grin. I left it on the kitchen counter so I could keep looking at it, but then the elation began to fade. Really, am I really pregnant? And worse, does it mean anything? This is my seventh pregnancy, even though I have just one little guy sleeping soundly in his bed. Is it ridiculous to think that I can have another one? Another soft downy head asleep on my chest? Screaming at two am, making funny grunts and coos nursing, learning to smile and laugh and walk and talk. I have been reminded that science is behind me- these embryos inside me are genetically tested, they are chromosomally normal, even though most of the embryos we made through our IVF process were not. It is possible, that this will happen. I hear that in Judaism, seven is sacred, and signifies completion. Maybe this seventh pregnancy is the one that will complete our family. I hope. I can hope.
