Is it bad that I am not happy what so ever that my sister is pregnant again? She had a baby in October and is now 13 weeks and that was such a horrible pregnancy that the baby almost didn't survive due to complications from her birth control that imbedded in her cervix. Not only that but her husband is abusive not only to her but to their other children as well. And whenever me or my other sister gets pregnant she goes and gets pregnant because she is jealous, she even admitted that when I was pregnant with Bryson. I just wish she would make better decisions for her family
