second miscarriage since January

MoeW528
I found out I was pregnant November 15, 2016 and went to the doctor December 8, 2016 at what would have been 8 weeks and the heart beat was slow. I went back to the doctor 5 days later and there was no heart beat. I decided to miscarry naturally and began on December 31,2016. I got my period on February 1, 2017 and found out I was pregnant again March 11, 2017. This time I went to the doctor at what would have been 6 weeks 6days to only find a sack and yoke. I went back 2 weeks later and there was a fetal pole and that was it. Tonight I went back to see if there was any growth and there was not so I am again going to try and miscarry naturally. Has anyone had any success stories after 2 missed miscarriages? I'm feeling a bit defeated
