Hello, I would be happy to help you with your question.
I am sorry about your prior loss. If the only two pregnancies that you have had are the two miscarriages, then there might not be a problem at all. While we start to worry when a couple has had two unexplained miscarriages, the definition of "recurrent miscarriages" is three unexplained first trimester losses. So, while you have obviously had some major difficulties, there really is not much of an indicated workup. But, your doctor should consider:
1. An ultrasound
2. Labs related to diabetes
, thyroid disease
, and something called antiphospholipid antibody syndrome
I hope that this helps and good luck - Please ask me if you have specific questions!
