Is it time?

Having a baby is starting to weigh heavy on my mind. Two of my friends have delivered healthy baby boys on the last two weeks. I thought Mr. Thinkin' and I should wait until the beginning of November to start TTC again. Holding those new tiny babies has changed my mind, and now I seem to have shifted into the "baby fever" mode. Mr. Thinkin' really wanted to wait until at LEAST September for work purposes, and of course those kind of things never set well with me. I love the financial benefits of him working all the time, but I don't like to think his career controls our lives. Who am I kidding?
I know that I shouldn't be worried, that we aren't pregnant right now, and that my body could probably stand the extra healing time. However, for some reason, I have this fear of never being able to have another baby. I loved being pregnant, I loved giving birth, and I loved all those sleepless nights I was learning how to nurse and care for my sweet new born. It is probably residual emotions left over from the miscarriage that this fear stems from. We stopped "being-careful" in January and here it is September and we still are not pregnant. I spoke in the Spring about needing to stop worrying and to remember that I am living on God's time, and being a control-freak just causes more problems. But where do you draw the line?
