Sorry to hear of your losses hun... :hugs:

I've had 2 m/c, so I know where you are coming from. It is a difficult time for you but remember to take care of yourself. DF & I went to the fertility clinic where I did a huge blood test (they took out 9 tubes of blood) but they couldn't find anything wrong. Although they just put it down as Coeliac disease (I'm allergic to gluten).
But look where I am now, 30 weeks pregnant & loving life. So there is always a light at the end of the tunnel as hard as that may sound.
