repeated miscarrige

Sorry for using english, I am not in Israel right now. the time with the embrio not developing correct, size too small or hurt stop. My wife had 3 times miscarrige, all aroung 8 week. The problem is all ilness from the Ureaplasma family and both of us were treated with Antibiotics. During the 3 rd time (now) our doctor found that we both have an ok. However, there is a problem with the embrio not growing after the 7 week. I understand that since we get to pregnancy, we probably are What could be the problem?

ron After 3 miscarriges you need to perform a set of tests in order to find the cause. There is a variety of possible causes, mainly chromosomal abberatins' as well as infections and so on.

Thanks for the answer. I was too fast with mentioning 3 miscarriges. We were at the hospital and they could see something growing! According to the size it can be early 7 week. We thought it should be 8 week, but my wife said that her period is longer and the beginning were around 21 days, not 14. So it is possible. We will be again at the hospital next week for another check... I hope it will be ok this time. What other problem can cause to a slow developed embrio?
