Ttc after 2 miscarriages

I had my first miscarriage in sept at 10 weeks- babies heart just stopped one day and baby never continued growing. I had to have a d and c. In December I had a blighted ovum and unfortunately had another d and c. I am wondering how long did you wait to try to conceive again? How long after your d and c did it take for you to ovulate again? How long did it take for you to conceive again? We are very anxious to try again and the drs just keep telling us both of our losses were bad luck. We were blessed with a healthy boy two years before our losses and are very ready to expand our family.
