All's I can say is I envy you beyond words, because you have a womb, I do not. (I am male in body, but not spirit. I've chosen not to change myself only due to the fact that I can't have kids. It's not worth it to me unless I can.

As for personal experience, I didn't know them extremely close, but I knew two kids that the following happened to.

They were both 15. The boy was quite pro-life, things got out of hand one evening, the girl ended up pregnant. She was of course very scared, but he got her to try doing an adoption. I'm not clear what happened, but she did end up having an abortion. She kept it hidden for awhile, but eventually I guess one of her 'friends' told the boyfriend about it.

He blew his head off with a shotgun the next day. Some time later, she commited suicide too, though it was never clear if the events were directly related.

That's my closest experience with someone that had an abortion.

And as I said, I believe it is a human being when it has its own DNA, this happens after conception.

Lack of nervous system doesn't mean anything to me. If you chop down a tree, is it any less dead just because it doesn't have a nervous system?
