Miscarriage!!!

Just lost my little bundle of joy on the 15th of April I am so heart broken this is my 3rd no kids in between or no kids at all but I have to go to a miscarriage clinic to go to was just wondering if anyone has ever been to one and dos they ever find out why you kept lossing your baby just hoping they find something and we can get something done about it and I can go on to have our baby that we have always dreamed of
