Advice please ❤️😔

Hello ladies .  My husband and I have been trying since July 2015. I got pregnant in march of 2016 but ended in MC after 5 weeks. I got pregnant again August 2016 but also ended in MC a week after I found out . My doctor has done blood tests and a internal exam with a camera but says everything is fine . I'm so sad and frustrated. I was also told I can't see a infertility specialist because I've been pregnant within the yr even though it ended both times in MC. Any tips or advice ?
