I have Factor V Leiden, it's a blood clotting disorder and is passed down from parent to child. I have it as does my siblings and every family member on my maternal grandfather's side.
It is quite a serious disorder and I have had one blood clot in my lung, all my family are on a low dosage of warfarin/heparin/aspirin to minimise the chances of blood clots.
I have 2 kids and they both have it as well. I was with a friend from university today and her kids and she was asking about it. When she found out that it is passed down from parent to child she got a bit shitty with me.
She said that she would never have kids knowing that they would have it and it could mean injecting yourself regularly and not being able to live a normal life.
I've been thinking about it and now I feel a bit 
because I look at my kids and can't imagine life without them. But maybe I was selfish to have children knowing they would have something that has caused me so many health problems.
What do you guys think?
