Advice?!

Amanda
So I'm not sure I'm even fertile. I was diagnosed with endo when I was 19 (2011) I had 3 laps @ 20 between may and august 2012 my daughter was conceived in November after she was born july (2013 6wks early) I was put on mirena from august (2013) until November(2014) my SO and I have been TTC since and Ive had 2 miscarriages. Would it be possible that I can only hold a pregnancy after surgery? Is there anything I can do to change that? Are there any all natural treatments?
