I think when you try again depends on how your miscarriage happened and how far along you were. For example, if it was a natural miscarriage at 6 or 8 weeks, I'd start trying again right away, as soon as I felt ready. In my latest case, I had a miscarriage at 17 weeks and had to have a D&C, meaning that I need to wait for at least one cycle for my uterine lining to thicken up again. Then again, after my first miscarriage at 7 weeks my doctor said to go ahead and try when we were ready. My body simply wouldn't get pregnant until it was ready to sustain a healthy pregnancy again. That was his advice. Do what you feel is right. Good luck.
