I have just had a second missed miscarriage and went through the exact same thing with the weak heartbeat then it had grown then nothing! They couldn't tell me why which as most of you know is one of the hardest things to comprehend!! It's been six weeks and just got my period which is sad!! Has anyone ever gone though a private clinic to start investigations? I don't think i could go into another pregnancy without knowing if there is anything wrong with me maybe i'm just hoping it can be something they can fix. Mu husband and i are both resus negative and wondered if maybe this is the reason our babies don't make it. Not sure if i'm just clutching at straws people keep saying you've just been unlucky and you'll be fine next time but i'm doubtful cause that's what everyone said the first time. would love to hear from anyone who's tried any investigations. We have no children and are just desperate for one no amount of drunken nights out or weekends away are helping we just want our family.
