Some folks are aware that it hasn't been the smoothest process at trying to get Hamish a little sibling, and this one has been a bit of a trial as well. Everything was going well until we got a combined test for downs that rated our chances a little bit too high, so we opted for the invasive CVS test to confirm what the situation was. The test carries a chance of miscarriage as a result of taking a sample of the placenta, but the chance was about the same as having a downs baby so it seemed the better option.
The good news, obviously, is that everything is fine, and goldengrove is out of the immediate danger period for the cvs test, with no significant side effects.
As a side effect of checking out the bump's chromosomes for trisomies, we also already know that we're going to have a boy :)
