unfair

I just need to say this somewhere away from friends and family to get it off my chest. My sister in law is pregnant with her second child, due in July. It's an unplanned pregnancy and not something she wanted to happen. This weekend I noticed she is still smoking. Her pregnancy is continuing just fine. Whereas I had been trying to get pregnant for almost a year, took extra precautions and tried to be extra healthy, and still had to deliver our twins stillborn at 20 weeks. It's just not fair.
