Two miscarriages in 6 moths TTC. Advice?

Hey there! I miscarried in June and then again in September of this year. My doctor is not that concerned and said they would not test me until third reccurent miscarriage. I lost both babies around week 6. I'm trying again since I have had my period and I feel pretty good. Also my ultrasound came out good. But I wonder have any of you had a miscarriage and then a healthy full term baby after? And if so what did you do? Any advice?
