OW - in regards to miscarriages........has she been checked for PCOS? It can cause a high rate of infertility issues......
If she hasn't been checked for that, they check her ovaries with a sonogram, and test her blood - they check insulin levels, hormones and thyroid I believe. There are more tests they can do to check her fertility but some are not pleasant - there is one to check her tubes and make sure they're clear - involves injecting dyes and from what I've read is MOST uncomfortable.
Have you had yourself checked?
