I know quite a few young ladies whom have had abortions and it has left them sterile, not positive it was the abortion or Gods way of letting them know you killed 1 or 2 or more so it tells me you don't want any children and indeed they are barren....the best to you
Abortion can cause scar tissue that make it hard to get pregnant and/or stay pregnant. A better type of birth control is the depo shot, patch or birth control pills. At least use a condom so you are not exposed to different diseases.
