After a personal experience with genetic testing (or lack thereof), I just wanted to urge anyone who believes they may be at risk of being a carrier (I know Ashkenazi Jews are at high risk, I'm not sure about other ethnicities) to please get tested before trying to conceive.
I naively thought that I would be fine and never got tested.
After my first OB appointment, where they take blood and ran tests for all genetic diseases, I found out I was a carrier for cystic fibrosis.
My husband had to get tested, and it has been a horrible 3 week wait to get his results.
Luckily he is NOT a carrier, but the wait has been so nerve racking, and I would not wish it upon anyone.
So please, do not go through what I did, and get tested if you are in a high risk group.
Even if you are both carriers for a particular disease, you can still have a healthy child through IVF.
Shabbat Shalom
