I have von will brands type 1. I was diagnosed when I was 16. I am now 44. I have two awesome kids. (18 & 21) when I was pregnant. My blood levels became normal...I was closely monitored and my delivery was planned so that the DVAP was on hand just in case. I was fine though and after 6 months my von will brands was back. Talk to your doc. It probably depends on type you have.
I think you should check out this problem sometimes such problems happens we can predict.
Don't know, but your first and immediate concern should be your own personal health. When that is figured out would be the time to worry about side issues, if any exist...that's how I see it.
