Miscarriage

Hi, is there any herbal formula that can help my body along with a baby that I've already lost? Some history: I had a miscarriage three years ago. I'd known I'd lost the baby but didn't actually miscarry for three months. I have now lost another baby but would rather not wait three months if at all possible. It has been about two weeks since I've known the pregnancy isn't legitimate. But, I think it had problems all along (no morning sickness).

Also, can I safely do a cleanse if I haven't miscarried yet?

Thank you!
