3 recurrent miscarriages

Hi ladies, unfortunately last month I went through my 3rd miscarriage in 8months all at only almost 6 weeks! Im only 24 and have no other children. My doctor is now referring me to a specialist to get checked out can anyone advise me on what checks they will do and how it works? I'm so scared there going to tell me something is seriously wrong! I really hope it's something that can be sorted so we can finally have our rainbow baby! Any help or advise would be amazing thank you ladies xx
