There are approximately 15 states with medicaid insurance coverage for abortion procedures done at any time during the pregnancy. If her current insurance does not cover it, she can look into it. Pregnancy related medicaid is different than standard medicaid requirements (higher income limits) and often provide coverage nearly immediately upon completion of the application. There are also donations available to help cover the cost. you can contact the National Abortion Federation for advice and information on where to go and what to expect. There are more clinics than just Planned Parenthood for services. OOP costs are usually $300-400 within the first 7 weeks. (Remember weeks start from the date of last period, so most women find out around week 4 or 5.)
Remember she still has the final say in all this. It ddoesn't matter what you want, only her if she goes through with it. Most clinics aren't exactly welcoming of guys because the fear the woman is being coerced.
