Repeated Pregnancy Loss

So I am looking for other ladies who have gone through 3 or more pregnancy losses. I had three losses last year and have never had any successful ones. We went through genetic testing for myself and my fiancé and now the right us have any chromosomal issues. They also tested me for the clotting disorder and nothing has showed up there either. The doctors have no idea why I have lost my babies and say it’s just “bad luck”. I am looking to see if any ladies have dealt with RPL and gone on to have a healthy successful pregnancy. Also if you have found anything that helps? I almost gave up and then it hit me that if there isn’t a reason why this is happening then there is no reason I can give up just yet. Any help is appropriated! Thank you ladies!!
