Ready to ttc but no cycle yet!!!

Good morning everyone. I miscarried on May 18th and had a d & c on May 19th. That was a very sad time for me. I have a 10 yr old daughter and my hubby and I had been trying for 9 yrs to have another baby. When I finally got pregnant, I miscarried. I know God doesn't make mistakes so it was all in his will. However, we're ready to start ttc again. My problem is the fact that I'm 38...not a spring chicken at all, but I'm willing to give it another try. I don't know if it's just me, but I feel the desire to want to become pregnant again. It's almost like a craving that I have but I don't want to become obsessed with trying. Does anyone understand what I'm saying? My question to anyone out there who has been thru this is, "how long did it take to get your cycle?" I'm very eager to start trying. We have been bd since my 2 week check up when my dr gave me the ok to have sex and it has been at least twice a week since then. I heard that you count the day of your d & c as the first day of your cycle and it can come between 4-6 weeks from then. I'm looking for answers and suggestions.
