Due to the circumstances surrounding the loss of Alex & the decision that we had to make, our OB atually offered to do chromosomal tests for us. This was in part due to the results of an u/s in which he thought that there may have been a chromosomal imbalance that may have caused our situation. However all test came back clear. So guess it really just was one of those things for us, hopefully not a thing to be repeated ~ fingers desperately crossed for this to be the case in another pregnancy.
