Frustrated with God's Timing

I learned today that my hcg is now negative - yay! No more blood drawings!! I told the girl from my doctor's office that it's been a month since I lost the baby & I haven't had a menstrual cycle yet. She said it varies from person to person (of course); some women start menstruating regularly right away while for others it can take several months. "Well," I said, "we were told that we should wait 2-3 cycles before trying again. So this might take a while, huh?" Yes, she replied, "but don't worry. It'll happen when it happens:)" (I added the smile because I am certain she was doing so on the other end of the phone. More so out of sympathy than optimism, though.) Not only am I extremely frustrated that I should be entering my second trimester at this time, but now it could quite possibly be another entire year before I get pregnant again! God, I gotta tell ya', I'm not too crazy about Your schedule.
