Vaginal birth after a c section

I am currently pregnant with baby #3. 1st baby was vaginal at 7lb and 2nd was c section at 10 lb. My doctor said fingers cross it isn't a big baby so I could try for a vbac but she also give me a paper to read with the risk of having a vbac. I got pregnant 9 months postpartum of c section. What was your experience of a vbac after a c section and how long after the c section did you get pregnant?
