Jennifer,
I am so very sorry to hear about your miscarriage. Having had one myself earlier this year, I know that nothing I can say will make you feel 100% better. Just know that you are not alone. It is so common! I swear, after having mine, people started coming out of the woodwork to tell me that they had one, too...both of my sister in laws, my aunt, my own OB, the lady at the checkout counter, the list goes on. It's almost a "right of passage" for women these days.
The good news is that you know that you can conceive, keep that in mind. The emotional loss can be very painful for some women, while others view it as "a bad genetic match" and are able to move on quicker. I had a very hard time emotionally with mine, I was depressed and cried a lot (especially because we are going through infertility treatments). I was that way for a few weeks, and especially had a hard time being around my friends (or strangers in the doctor's office) that were pregnant. Not to mention your hormones are "adjusting back to normal"... When I thought I was "over it" about 3 months later, I found myself bursting into tears without warning, and when I mentioned to my Mom that I "thought I was over it," she said "M., losing a baby is something that you will never truly get over, you just move forward." I find this to be true. For me. Other women are vastly different.
In terms of waiting, it all depends on your doctor, age, and your body. I had heard to wait 3 months, but since I am 38, my doc only told me to wait one complete cycle before trying again. My first cycle after the D&C was a bit irregular, the bleeding started as spotting for a few days, then a flow that was different than my "usual" periods. One month after that, my cycle was back to normal.
The actual D&C I had done at Prentice Women's Hospital. The staff was great, and very sensitive to the issue. Just be warned that they might talk about dates of conception, and make you sign something that refers to "products of conception" (like do you want them to be tested in the lab). The procedure itself is relatively quick. They put me in a waiting room, called me back to a private dressing/recovery room, gave me an IV, a drug to relax me, wheeled me into the operating room, then once on the table in the OR gave me another drug that did not put me to sleep, but made me forget the entire procedure. I remember that the room was cold (I wore an exercise bra with no underwire and warm slipper socks with the gown). I remember seeing the table, a tray with tools, and <warning> the suction device, and an ultrasound machine. I do not remember any of the procedure at all, and just remember waking up in the recovery area somewhat upright, with those "hospital panties" now on, covered in blankets. They let me stay there with my husband until I felt well enough to get dressed. Then they wheeled me out to the car. Recovery wasn't bad, crampy and bleeding like a period for a day or two. They might give you perscription pain meds if you want them. If you can, I recommend that you have someone there to stay with you if you anticipate needing emotional support. My husband went to work the next day, and I got very depressed on my own. Another thing that I did not consider in advance is that my husband would be sad for the loss, too. I just wasn't expecting it.
I don't know if there is a way to find prior posts on Mamasource - I was worried about having a D&C vs. having a natural miscarriage and posted a question which received 40+ replies last end of June/early July. In a nutshell, a few of the moms said that the D&C is less painful than a natural miscarriage (which can drag out over weeks, and they want you to bring the "tissue" into the office sometimes). Some of the moms prefered letting it happen naturally, while other moms said that they needed a D&C anyway because their bodies did not pass everything on its own. If I ever, God forbid, need to do it again, I would definitely do the D&C without hesitation. Over and done with, and on the road to recovery.
Hope this helps. You are in my thoughts and prayers. And here's to a quick recovery. Lots of hugs to you.
M.
