According to Lori over at feministing, an anti-choice group known as Abortion Changes You has put up ads in NY subways playing the whole "You'll regret it!!" tactic.
Nevermind that, pregnancy? Changes the crap out of you. Especially when it's forced, and you don't want it.
Women get a range of feelings after getting an abortion. There is no evidence that post-abortion syndrome exists.
Wish we had the level of funding to be able to paper our as everywhere, unfortunately our funds tend to go towards helping women, which costs significantly more than scaring the crap out of them.
