Is there a way to find out if my wife had an abortion secretly behind my back?

I supect my wife to have been leading a double life outside our marriage. (phone hangups, disappearing for hours, no interest in me or family activities, no , no kissing ect ect) I had a vasectomy 10 ago. I caught her taking birth control pills without my knowledge 2 years ago. Insulted, I demanded that she stop taking them. Months later I noticed her belly unusually "bloated". Not the usual bloating ociated with monthly periods. We are now going through divorce after an acculmulation of things on her part that I just can no longer deal with. I let it go on for years hoping that things would get better. Now that I have the strength to file for divorce, she is bitter. Had her cake and ate it too. She's playing the divorce game. Trying to make me suffer.
