I am also 25 I have 2 daughters 4 and 1, I was terrified to go in, I asked God to send me a sign if this was a go or NOT. My grandfather was dying and was due to pass away the week before nobody thought he was going to make it even by the hour...WELL he did he made it 1 week and the funeral was Thurs, this was my sign that it was OK nobody was torn on where to be there with him or the family or with me, If you ask God he will send you somthing to let you know it is ok. You do have to pay attention and unerstand but it will come.
The medical aspect is the Dr's have MANY ways of preventing things from happening, I now thank God I did this even thought the morning of I wanted to breadown on the way so I didn't have to chicken out!LOL It will all work out and GOD works in mystereious ways if your not meant to do this HE will prevent it!
Best of luck!
