Hmmm... Reasons for abortion:
1) I'm too young to have a baby.
2) If I have a baby now, it will interfere with my college plans.
3) The father of the baby doesn't want it, and insists this is the best thing.
4) I don't want to go through 9 months of pregnancy, give birth, and then give it up for adoption.
5) I don't want my parents to know.
6) I have AIDS (or similar disease) and don't want to risk passing it on to a baby.
7) I'm a drug addict, and don't want to pass that along. (A rather contradictory reason, conflicting responsibility with irresponsibility.)
8) My husband and I already have 2 (or 3, or 4, whatever) kids and simply can't handle another.
9) We didn't think I could get pregnant this soon after giving birth.
10) Fetus testing showed a likelihood that the baby would have birth defects.
11) There is a genetic disorder (such as Cystic Fibrosis) in my husband's and my genes combined that would make this a strong possibility.
12) I got pregnant, and my boyfriend/husband walked out.
13) I'm lesbian, and got pregnant so that my significant other and myself could have a baby. She walked out on me.
14) The pregnancy would ruin my figure.
15) A baby would interfere with my career plans.
16) The pregnancy resulted from a promiscuous episode.
17) The pregnancy resulted from a night I got too drunk.
18) The pregnancy was a result of rape.
19) The pregnancy was a result of incest.
20) I was diagnosed with a serious medical condition (previously undiagnosed heart condition, cancer, etc.) and carrying the baby to term would risk my life. I've other children and a husband to think about.
21) I was forced to have one by my parents.
Well, that's all the ones I can think of off the top of my head.
