Can you abort a 3-4month old fetus?

Depends what country you are in? But in the U.S., first trimester (0-12 weeks) and up until viability is legal (about 24 weeks).

However, some states Kansas, N. Dakota have passed laws banning abortion at 6 weeks, though judges have put HOLDS on those laws. But check for your state at Alan Guttmacher Institute or call the National Abortion Federation for most accurate info.

Also, only 10 states have an abortion provider from week 15 and you find them at abortion dot com.
